I'm great at making late night food. My partner have a five minute patience. I'd recommend a low carb tortilla in a pan on the stove..heat it up, sprinkle it with mozz cheese or even sliced cheese will do. add sliced meat, chicken, or really any leftovers that you feel like eating.
If I'm making a ham and cheese, I like adding spicy mustard.
If I'm making chicken and cheese, I use some sort of spicy sauce.
If I'm making a steak and cheese style, I use mayo.
When the cheese is melted, fold the tortilla back onto itself. the cheese seals it together. I'd recommend getting your condiment in there before you seal it up.
Take it off the heat and slice like a pizza. ..perfect finger food for late night and not too bad for you. I've yet to hear a complaint.
