Don't forget sloppy joes.
Or make-your-own pizza.

All of the above.
Plus,
Chili.
Burgers, dogs, & potato salad (or slaw).
Big pancake breakfast (with scrambled eggs and either bacon or sausage).

I always make large pans of food, and go Italian. Pan of stuffed shells, baked ziti, lasagna, salad, garlic bread. Pan of brownies, few trays of cookies, cut up fruit, ice cream.

If it will make your house too hot to use the oven so much, then I'd grill hot dogs, hamburgers, steaks, chicken cutlets, veggie kabobs, peaches, etc.

Sliders - always delicious
