I have a similar problem, since I’m vegetarian, my mother gets heartburn from spicy foods, and my brother doesn’t like vegetables. It seems like it’s impossible to cook a meal that we all like! Actually, what usually ends up happening is that whatever I cook satisfies two of us and the other one can at least tolerate it, and since it rotates like this, no one starves.
Another technique that I use is to cook two or three small “side dishes” instead of one big entree, so we can pick and choose.
Cooking always requires creativity. This is just another type of challenge.
