When I used to make purim Seudah, this was my menu:
1. Fruit cup on the table at each place: Easiest one I know-pineapple tidbits, mandarin oranges and frozen blueberries
2. Stuffed cabbage (it is a purim minhag)- I make it with purple cabbage because that does not have to be checked
3. Chicken soup with kreplach (another minhag)- I use Mazor ravioli dough, it makes them much easier
4. Main course: Chicken-doused with duck sauce, covered and baked for a long time (at least 3 hours), rice, green beans
5. this was our fun course, my husband wanted time to sing (& drink) after he had real food in his system but didn’t want to sit with chicken bones on the table, he also felt dessert meant it was time to bench, so we came up with this course. After the main, we cleared the table and brought out “finger foods”: franks and blanks, mini knishes (meat & potato), kreplach, homemade pickled veggies (usually beets & eggplant), and anything else along those lines. everyone always loved it
6. dessert: Hamentashen!!! The only appropriate purim dessert.
We used to make seudah for 30-40 people. In case you think this is complicated I used to live in a 1-bedroom apt with a TINY kitchen, with some advanced preparation this seuda is really not hard.
