Quesadilla Casserole

This recipe was actually from the McCormick seasoning packets. Super easy and super delicious! I will put

2 tsp Chili Powder
1 tsp Ground Cumin
1 tsp dried Minced Garlic
1/2 tsp dried Oregano Leaves
1/2 tsp Crushed red pepper (optional)
1 lb ground beef
1/2 cup chopped onion
1 can (14.5 oz) diced tomatoes, drained
1 cup salsa
1 can (15 oz) black beans, drained and rinsed
1 cup frozen corn
6 flour tortillas
3 cups shredded cheddar cheese

1. Brown beef and onion in large skillet on medium-high heat; drain. Add diced tomatoes, salsa, beans, and corn. Mix well. Stir in all of the spices except red pepper. Bring to boil. Reduce heat to low; simmer 5 minutes. Add red pepper to taste if desired. (I don't add it since the salsa is usually spicy enough and I have little kids).
2. Spread 1/2 cup of the beef mixture on bottom of 13x9x2- inch baking dish sprayed with no-stick cooking spray. Top with 3 of the tortillas, overlapping as needed. Layer with 1/2 of the remaining beef mixture and 1/2 of the cheese. Repeat with remaining tortillas, beef mixture and cheese.
3. Bake in preheated 350 degree oven for 15 minutes or until heated through. Let stand 5 minutes before serving.
