Generally, I have a quesadilla for breakfast. I am not a morning person and always am late to work...but no one cares. I make my quesadilla usually just two tortillas and cheese, Sometimes I spice it up with some salsa or hot sauce, or if I'm really hungry I'll add some leftover meat. Anyway, I have it timed so that I can start my quesadilla and go get finished getting dressed, come out and flip it, and put my shoes on and then it's ready to go.
I used to eat an egg sandwich for breakfast every day...or oatmeal...or cheerios, until I figured out that I have food intolerances...to eggs and oats. No wonder I had issues every day....for decades. Ugh.
My favorite cheat breakfast is a sausage and cheese mcgriddle with a hashbrown and a diet coke.
About once a month I do get some JUST Egg, which is mung bean paste made to imitates scrambled egg. I like the new frozen servings, you can cook them in a toaster. They make a nice 'egg' sandwich.
I am starting to get bored with quesadillas, so I'm thinking about going back to protein shakes, milk, banana, a mix of spices, and maybe some yogurt. I did that for several years when if first figured out my egg issues.
