cooking for a friend who is vegan and gluten intolerant - and I'm allergic to coconut!

How about tempeh ?

Salad and a vegetable soup would work for a main dish. You could add a gluten free grain to the salad. Or, make vegan chili and corn bread.

Do you have a particular meal or type of food you'd like to cook?

With dietary restrictions as you stated, I'd ask your friend for suggestions. It will help give you a guideline.
