Coconut milk-based curry with just vegetables or tofu.

But the pasta could work. Add a salad, and bread with a vegan butter or olive oil option.

Fish!!

We made this the other night and it was awesome:

We used the chicken, but obviously you'd use the tofu. Both directions are in the menu.

We also didn't use peanuts because we have that allergy in our family. I'm not clear if your list is the entire list of allergens, or if you are avoiding all major allergens. If so, this won't work since sesame is on that list.

Middle eastern platter of salads (tabbouleh, baba ghanoush, fattoush -- either use GF pita or veggies as dipping vehicles) and sides (roasted eggplant, zucchini, etc, using pine nuts, harissa, herbs, for extra flavor -- and rice if you want a designated starch). Serve feta on the side if some people would like it.

Main dish is falafel (we use Mark Bittman's recipe).

You can make everything in advance and serve cold or room temperature, or everything ahead except the falafels.

GF pasta puttanesca

tacos with corn tortillas--I would do refried beans, roasted veg, pico de gallo, etc.

a potato-crust quiche (many recipes online) would work well--this time of year I would use zucchini in it. Just use a non-dairy milk; unsweetened oat milk is a good thickener. Serve with a nice green salad.

A sweet potato and black bean chili would also work well. There are GF cornbread mixes.

Or maybe roasted/grilled eggplant, summer squash, onions, and the like with a chickpea and rice pilaf. Serve olives and hummus and veggie sticks on the side.

Unless there are major allergies, you could also adapt several of these by adding side items like meat, cheese, etc.

Stir fry with either rice noodles or cellophane noodle — pancit, pad Thai, or jap chae.

Use the noodles and veggies to make lomein.

Another roasted veggie on the side if you need something else.

You need a GF vegan main dish? Just vegetables and rice.
