What about BBQ? You can do sliced or chopped and beans and a salad.
Also, lasagna or spaghetti with green beans and a salad.
Good luck!
Wow......that's a lot of rules!
What about a Pot Luck? You just have everyone bring a dish that they bought from the grocery store. Since technically that's NOT catered.
Now you just need to figure out what grocery stores around serve and then delegate. Assign people what type of dish to buy. Such as people with last names starting with the letters A-H bring a healthy main dish,then I-Q bring a vegetable side dish,then R-W can bring a dessert. And then X,Y,Z can bring drinks,cups,utensils,plates,napkins etc etc.
