Quesadillas don't get any easier than this. Top two flour tortillas with canned refried beans, shredded Mexican cheese, taco sauce, and two more flour tortillas. Microwave and cut into wedges for a snack or light supper.
Spread beans evenly over 2 tortillas. Sprinkle evenly with 3/4 cup cheese, and drizzle with 1/4 cup taco sauce. Top with remaining tortillas.
Microwave 1 quesadilla, covered with a paper towel, on a microwave-safe plate at HIGH 1 to 1 1/2 minutes. Repeat procedure with remaining quesadilla.
Cut each into 8 wedges; serve with remaining 1/4 cup taco sauce, sour cream, and remaining 1/2 cup cheese.
