To a medium sized bowl, add the beans and mash with a fork. Then add the rest of the ingredients and stir to combine well.
On one side of the tortillas, spread the mixture evenly. Then fold over the other side to make a quesadilla.
Heat a skillet on medium-high heat and add the tortillas. Allow to cook for 3-4 minutes until browned and then flip to cook evenly on the other side. Enjoy with a side of salsa, avocado or guacamole!
