You could take the things to make a sort of quesadilla in the microwave. Take a small fajita sized flour tortilla (whole wheat and/or low carb if you are worried about that), 1/4 c shredded cheese, 1 or 2 oz lean meat, and a little salsa. Lay the tortilla flat, top it with the cheese and meat, nuke it for about 35-40 seconds until the cheese melts, then garnish with salsa. Fold it in half and enjoy! Depending on how much meat you have, how thick it is, etc., you might heat that up mostly first and then put together your tortilla for nuking so the meat isn't too cold.
