T.S.
I find it funny how so many people can't think outside the egg-cereal-pancake breakfast box LOL :-)
Breakfast doesn't need to be "breakfast" food, they can eat anything! I often eat leftover dinner for breakfast, warmed up, and sometimes my kids do as well, especially if it's a favorite soup or stew, or fried chicken. You can make them ANYTHING they like, sandwiches, wraps, grilled cheese, pasta, you name it. My kids LOVE when I make fried rice for breakfast with leftover pork, or ham. Cook some rice, sautee the chopped up meat with finely diced onion in a skillet with a little oil, throw in a few peas and carrots, scramble an egg or two in there, add the rice and a bit of soy sauce (not too much!) and voila, once it's gently mixed together it's complete and satisfying hot breakfast. Since it's just as good at room temp they often take it for lunch as well.
