Black Bean and Cheese Quesedillas

I'm always looking for great tasting, frugal meatless meal ideas.  Here is one that I use often and we really enjoy!

2 c. prepared black beans (soaked and cooked or use one 15oz can black beans)
Use a potato masher or your food processor to make "bean paste"
Spread bean paste onto tortilas (homemade whole wheat tortillas are great!)
Sprinkle with shredded cheese (we like colby jack)
Place another tortilla on top
Bake at 350 degrees for about 10 minutes, or until cheese is melted
Cut into quarters and serve!
We top with Ranch dressing and spinach (also really good with salsa if your not nighshade free)
