I know, duh. But being this is a blog about cheap food, I have to add it :)
-a carton of eggs
-whatever is in your fridge: leftover ham, cheese, peppers, mushrooms, bacon, etc.
Scramble that shit up! Crack open them eggs and throw in some cheese and whatnot, and them put them in your pan and go to town. DONE. And if you wanna get fancy, make it into an omelet.
I am allergic to eggs, but make this for my kids. Cheap. As. Shit. Breakfast.
Whip up some toast while you're at it.
