Shredded 2% mild cheddar cheese
Sliced red onion
Pulled barbecue (I used Cades Cove brand, which I found in the refrigerated meat section)
Heat barbecue according to directions on the container (unless you've made your own barbecue in a crock pot). Spread barbecue in a thin layer over a tortilla, leaving about an inch around the edge. Sprinkle well with cheese, top with onion, then put a 'lid' tortilla on top.
Put in the quesadilla maker for 5-10 minutes until it is golden brown and hardened. Remove from quesadilla maker, let cool a little, then cut with a pizza cutter.
With this type of quesadilla, you could serve it with corn or other type of veggie or black bean salsa, but these are SO filling that they can just be served on their own. They look thin, but there is a lot of meat and cheese in each one! I usually split one with someone else and only end up eating 3 pieces.
