Using only leftovers from other meals and tortillas I keep on hand todays lunch was chicken mushroom spinach quesadilla. Cost was $0 since I reused leftovers and everything was bought and figured into other meals.
I am determined not to waste any leftovers.
1/2 cup spinach
1/4 cup mushroom
1cup grilled chopped chicken
Topped with sour cream, tomato, jalapeños. And more cheese.
