I love brats with sauteed onion and bell peppers, just put them in a pan with salt and pepper and butter or oil and cook until they're tender. This can be done on the grill as well. Other things that go with them are baked beans, potato salad, potato wedges, tater tots, onion rings, macaroni salad, and coleslaw. Canned is fine for all of these things, but can be made easily and fairly quickly as well. You can definitely eat the brats on buns like a hot dog, my family never eats brats without buns, but you can if you'd like.
