My team really likes garlic bread.

My mom often bakes a lasagna from Costco and makes a salad.

Another popular dish is macaroni and cheese.

The bread rolls from Costco, with ham and cheese is another thing my mom has made.

My team mostly has nut allergies—not sure which allergies you meant when wanted recipes good with allergies. Dessert is nut-free but is often cross-contaminated with nuts. We usually have some sort of nut-free snack food around, and not getting dessert is pretty normal for people with severe nut allergies. (In case it isn't clear, that includes me.)

We have parents bring dinner all through build season, with usually a vegetarian dish, a meat dish, and some sort of dessert sometimes. Usually three or so parents bring dinner per night, as we have a large team. Dessert is usually simple—some fruit, or a box of individually wrapped brownies.
