Need ideas for company dinner

[esperanza]

We are having some friends over for dinner this weekend. One adult and one child are vegetarian. The other adult likes meat and can only eat it out of the house. Dh can't do dairy and also loves meat. He sometimes has gas with beans, and he can do queso fresco. When we go to their house, they usually do individual pizzas. I have done build your own burritos, which I may do again. I was also thinking of pasta, but that isn't very exciting. Basically pasta with sauce and optional meatballs. Thought about nachos but that doesn't work well for dh. Bonus points if it is something I can prep ahead of time. Doesn't need to be fancy. Good friends, casual dinner. Any ideas? I like the build your own style because people can make what they want. I have never done a baked potato bar. I like that, but not sure that is enough for the two men who like to eat big meals.
