I make a similar breakfast burrito.
When things are tight, eggs and some of Momma's home made salsa.
We splurge when we had a little bit of sausage to the above.
Usually just nuke the tortillas in the microwave.
For quesadilla sprinkle a little bit vegetable oil onto a warm skillet, toss a the tortilla on there for a minute, add some cheese, chicken, whatever you like, throw another tortilla on top, flip, cook for 60 seconds. Result best daddy in the world.
