Preheat oven to 375 degrees
Dice the peppers and onions. Heat olive oil in a large skillet and add diced peppers and onions and cook until tender. Remove from the skillet and set aside.
Brown your ground meat in the skillet until cooked through. Add Rotel, cooked onions and peppers, corn, and southwest seasoning to the meat. Simmer for a few minutes.
Spray the bottom of a 9×13 pan with cooking spray. Line the bottom of the pan with 8 tortilla halves and spray tortillas with a bit more cooking spray. Then spread with half of the refried beans, then layer 1/2 of the meat and vegetable mixture over top.
Layer the remaining 8 tortilla halves on top of the meat mixture and repeat the directions above.
Sprinkle the shredded cheese evenly over the top.
Bake at 375 for 30 minutes, or until heated through and cheese is hot and bubbly.
Top with optional diced jalapeños, fresh cilantro, avocado, Greek yogurt and a squeeze of lime and enjoy!
