The foods of pascha are indeed a "t"radition. The Greeks serve Margaritsa, roasted lamb, and braided pascha bread. The Antiochians and palestinians serve roasted chicken with pilaf, sweet bread, mahlmoud, and sweets. The Slavs serve the pork and sausages, Bobkha, sweet butter and horse radish. What Americans serve has yet to be determined.
I must admit that the traditions of the Slavs with their pascha baskets has developed a certain symbolism that has embued their traditions with meaning. This is from the Orthodox Family website and is an explaination what the items placed in the basket mean to Ukranians who have learned how to prepare these foods, and what they meant:
"1) Pascha, a rich egg-based bread sweetened with raisins, represents the "Bread of Life", Christ. My family always baked half a dozen paschas in small coffee cans, so they were round when you sliced them. [My Grandma always turned the pascha over before she cut it, and said, "In the name of the Father, and the Son, and the Holy Spirit," cutting off three small pieces from the bottom as she did so. These pieces were put on the window sill to dry out, then eaten throughout the year, like Holy Bread, when one of us was sick.]
2) Christ's Biscuits, were small round rolls made from the same dough as the pascha, brushed with egg as they were baking so the tops were shiny and deep brown. They always had icing crosses on the top. Again, they symbolize the Bread of Life.
3) Pysanki, decorated hard-boiled eggs, are a symbol of the Resurrection: Jesus came out of the Tomb just as a chick comes out of an egg. My family always had bright pink eggs dyed with onion skin (like the one Mary supposedly offered to Pilate when she visited him after the Resurrection), and eggs decorated with pussy-willows, crosses, swirls, and "Christ is Risen! Christos Voskrese!" [As children, it was our job to prepare the eggs using the pysak (a "quill pen" for applying melted wax to eggs) my Grandfather had made before he died. My mother always removed the wax after the eggs were dyed, because she never scorched them! Depending on how close to "western Easter" it was, we would use an egg-dye kit for some of the eggs, so our baskets sometimes included marbleized, glittered, or Mickey-Mouse eggs as well. We never included the glossy black "Ukrainian" eggs made with toxic dyes, even though we made them throughout the year for show. Basket stuff was meant to be eaten!]
4) Kielbasi and Ham are in the Pascha basket to symbolize the sacrifices made before Christ's perfect sacrifice; they are the basket's allusion to the Old Testament. I've recently read that meat in the Pascha basket also symbolizes the calf sacrificed when the Prodigal Son returned home; the meat is a celebration of our return to Christ.
5) Horseradish and Spicy Mustard are included in the basket to remind us of the bitter drink given to Christ at his crucifixion, vinegar and gall. [My Grandma sometimes dyed the horseradish pink with beet juice, to symbolize the Blood shed by Christ.]
6) Butter, usually whipped and flavored with almond, was included in the basket to symbolize the Lamb of God, the Sacrifice made for the world. [Some families used a lamb-shaped mold for their butter, which made the symbolism even stronger. We leave ours in a block, but carve a cross into it.]
7) Salt, which was traditionally used to preserve food, represents the Truth of his eternal message. [When I married, my Grandmother gave me a special crystal shaker for my basket salt as a gift; she has used her shaker for over 70 years!]
Egg-cheese (actually called "rrrroot-KA", which might be spelled "hrutka") was the adult's favorite basket food; it was a rich, sweet scrambled-egg lump that they sliced, salted, and ate cold on pierces of pascha. [I have never tried to make it myself, but have my Grandma's recipe.]
9) Sweets: Our family's Pascha basket never included chocolate or other candies, but I plan to slip in a chocolate egg and marshmallow lamb for my 18-month-old daughter this year. The symbolism is there, and as long as she grows up knowing the meaning of the foods in the basket, the sweets will never be confused with the plastic Easter baskets filled with sugar and stuffed rabbits sold at K-Mart.
10) The foods were prepared and loosely wrapped, then displayed in a sturdy basket so everything could be touched by the Holy Water when blessed after the Resurrection Liturgy. A decorated candle (and matches) were tucked into the side of the basket, and it was covered by an ornate cloth. The full basket was heavy, so we didn't worry about it tipping over in the car. "
To this we might add the tradition for the triple braided Pascha Bread of the Greeks representing the Holy Trinity and the One God.
These traditions are used by people because they are meaningful to those who do it, however if the tradition becomes more important than the reason it is wrong.
Where will the American (or Canadian or Australian) Orthodox go with their Pascha traditions who knows? Maybe someone can figure a symbolic reason for the eating of KFC or pizza or Burger King hamburgers---oh wait there is a reason ---It is the Feast of Feasts when we no longer fast and repent in sorrow but celebrate the joy of the resurrection of the Lord! According to St John Chrysostom:
"You rich and poor together, hold high festival!
You sober and you heedless, honour the day!
Rejoice today, both you who have fasted
And you who have disregarded the fast.
The table is full-laden; feast ye all sumptuously.
The calf is fatted; let no one go hungry away.
Enjoy ye all the feast of faith:
Receive ye all the riches of loving-kindness. "
