Sandwiches are always a good alternative, too. You can make a vegan spread or buy hummus. Add a variety of: lettuce, sprouts, tomatoes, onion, beet slices, homemade non-vinegar pickles, etc. You can also mash beans with the vegan spread for sandwich fillers.
Last potluck had a delicious vegan spread: rice & nut dish, mashed potatoes, crocks of soups or beans, bread stuffing, burritos, chips & cheese sauce, salad, homemade bread & vegan butter and vegan desserts: gingerbread cookies, pumpkin pie & honey buns. Sometimes the problem isn't what is there to eat, but to remember to control yourself when it is all healthy. One member also makes an effort to bring something soy-free for me - imagine, vegan & soy free! that's not easy to find. He made the most delicious vegan mexican dish for yesterday.
