Pancakes. Flour, sweetener, leavening, liquid. Usually that means sugar, baking soda, milk, and egg, but in my experience, substitutions usually work out. Combine sweeteners and add vanilla for extra credit.
I made some fucked up pancakes for lunch today. Used very little baking soda, so it was more like a flatbread, then I fried some bean patties and basically had a pancake sandwich? It was super ugly but it was awesome.
You want choices? One of my easiest is rice+whatever. If I want greasy food in the morning but I'm too lazy to make a sandwich, I throw bacon and eggs into fried rice and call that a meal. It's genuinely incredible. You can basically throw anything into a pan with rice and it will probably work out
