Chop your veggies, and saute the red onion, red pepper, garlic and corn over medium heat until the onions are translucent.
Heat up the beans, and add a couple teaspoons of taco seasoning until the beans are as spicy as you like.
Meanwhile, add a couple teaspoons of taco seasoning to the veggies, and add in the spinach.
Start assembling your “lasagna”! In an 8×8 baking dish, start with a layer of the tomato sauce, ⅓ of the salsa, and a layer of the corn tortillas.
Top the corn tortillas with ½ the refried beans, ½ of the veggie mixture, and a drizzle of the tomato sauce + salsa.
More layering – top with the corn tortillas, the remaining ½ the refried beans, and the remaining ½ the veggie mixture, a drizzle of the tomato sauce + salsa.
Then top with the corn tortillas again, and the rest of the tomato sauce + salsa. Top that with the cheese, olives and tomatoes, and it’s ready to go into the oven!
Bake at 350 degrees for 15-20 min, until the cheese is bubbly and melted.
