We do this at my Serbian parish. The Russians often have the traditional Russian things, but I read once an article that said what should be included in any ethnicity's basket, and encouraged people to make the Pascha Basket their own. My heritage is German, so our basket reflects that. It said to always include:
An Easter Bread, symbolic of the Eucharist (most cultures have a traditional one. I make the German osterzopf. Some people also think you should add wine for the same reason)
Some kind of cheese, to represent peace (I don't get the connection, lol, maybe because nothing is harmed in the making of cheese? We have a cheesecake-like cheese ball)
Some kind of meat, as a representation of the old sacrifices (we use bratwurst, some people use lamb)
Some kind of pork, to represent that we're no longer under the Old Law.
Salt, to represent all that salt traditionally represents
Butter, shaped like a lamb if possible, to represent the Lamb of God
Something bitter, to still recall the sorrow of our sins (we use sauerkraut and mustard. Lots of people use horseradish)
Red eggs, of course, to symbolize the Resurrection.
Candy and sweets, to represent the love of God and our joy in Him.
Following that outline any culture can substitute traditional foods and do the Pascha basket. There's also always things that people have been craving and have given up. Ours will have Dr. Pepper in it, for example lol, and I've known them to include buffalo wings, ribs, or lasagna. You always stick a candle either in the cheese or the bread to be lit for the blessing. Last year, our first Pascha as a married couple, my wife cross-stitched a basket cover for us that we use.
We bless ours in the breezeway between the hall and the temple, and then everyone goes to a back room to share food and dig in. We get home around four or five usually.
I know the Greeks down the street share a common meal of lamb soup, but they don't do baskets. Some of them come to our parish to do baskets because they love the tradition.
