I'm cheap, and I also have barely any time for breakfast in the morning, and my wife likes it when I make her breakfast but she leaves for work an hour after me.
So this is what I do, and have done for almost three years straight now.
You get yourself some Some And a big bag of shredded cheese, your choice
First thing I do when I walk into the kitchen is start the toaster oven, getting it hot. Then I take a chicken patty out of the freezer and break it in half on the edge of the counter while it's still in the bag. Then I take a half sheet paper towel, and fold it in half, because I hate doing dishes. I put both halves of the chicken patty on it, pop it in the microwave for one minute, 30 seconds per half if I'm only doing one. Then while that's going, I slap two tortillas on the counter, sprinkle a healthy dose of cheese on them and spread it out evenly. By the time I'm done, so is the chicken, so I put each half on one side of each tortilla. Next comes the flavor. You can sprinkle a little garlic salt and pepper, or a dash of worcestershire, or my favorite was a dab of Chick-fil-A sauce under the patty. Then, slide it onto the rack in the piping hot toaster oven. Then I walk away to go start getting ready for work, just a simple task like finding socks or something, then I come back a minute or two later and the cheese is nice and bubbly, the tortilla is browning on the edges, it's just about ready to pull out. Then I pull them out, fold them in half, put mine on my water bottle to cool, and hers goes back into the toaster oven, but it's a fancy oven so I set the temp to 160f so it's nice and hot when she gets up, but doesn't keep cooking too much.
The whole process takes less than 10 minutes, maybe even 5 minutes if I'm really on my game in the morning.
The whole thing costs like 50 cents, and is plenty filling for me. It's probably not the healthiest option, but.. 🤷♂️
Why don't I use something more breakfasty, like sausage? Because I can't find it as cheap as the chicken. Funny enough, I actually started this whole process during COVID, with frozen precooked sausage patties. We got a bag of them with one of our low income commodity boxes, and couldn't figure out what to do with them. So I started doing this. Then when the bag ran dry, I transitioned to chicken. Not as good, but still good, and like I said, I'm cheap lol.
Hope this helps!
