Quesadillas.
On the higher effort end: whatever protein that has to be cooked plus onions, peppers, garlic, seasonings, and cheese. Then pan fried in whatever fat is left over from cooking the protein, adding butter if there isn’t much fat like with chicken or turkey.
Medium effort: still pan fried but using canned chicken or any Mexican style meat that I’ve frozen.
Barely any effort just need to get food made: same as the medium effort but put together then tossed into the toaster oven until everything is melted.
Add salsa and chips and call it a meal. It may not be healthy but it’s basically my go to when I don’t want to put in the effort of cooking something as I always have everything on hand.
