So basically, I cook two nights a week for a household of four adults including myself. Here are their dietary preferences: Person #1) Eats no meat, but seafood ok. Person #2) Eats no meat, seafood, eggs, cheese or fermented items. Person #3) Dislikes veggies, ethnic foods, and dishes with a lot of sauce. No tofu (this makes feeding persons 1 and 2 very difficult). Loves meat. Person #4) Dislikes cooked veggies (raw ok) and tofu. Dislikes onions and peppers of any kinds. Usually I end up making a meat-n-potatoes dish one night a week to satisfy diners #3 and 4, since the no-meat rule of diners #1 and 2 is a dietary thing, not moral/ethical, so they are okay with me picking out chunks of meat from say, a stew, and replacing it with veggie meat in their plates. The other night I make something vegetarian - squash as a main dish or something with lentils and beans. As long as there's no tofu, diners #3 and 4 will eat it, albeit with little enthusiasm.
