This is the fastest (and one of the healthiest) recipe in my repertoire. It's perfect for those nights when you just don't feel like making anything but still want something nutritious.
1 bunch Swiss chard, torn into small pieces
4 tortillas, whatever you like
1/2 cup or so feta cheese
1 clove garlic, finely chopped
salt & pepper
few splashes Franks Red Hot sauce
1 TBL or so water
Place one tortilla in a pan over med heat. Add 1/4 of the feta on top of tortilla then 1/2 of chard. Sprinkle 1/2 of garlic, hot sauce, and salt & pepper to your liking over chard. Add another 1/4 of the cheese. Place another tortilla on top of all this. Add a small amount of water (about 1 TBL) to the pan and cover for a few minutes. The water will steam the chard. Flip the quesadilla and cook, uncovered, for another few minutes. Both sides of quesadilla should be slightly browned. Cut into 6 triangles. Repeat for 2nd serving.
Subs: spinach for chard, any cheese for feta
Add ins: mushrooms, tomatoes, cilantro, sausage or any cooked meat, salsa, corn...
