Sauté the chopped spinach in the olive oil for 2 minutes or until wilted.
In a bowl combine the spinach, cumin, green onions, cilantro, corn, beans, 2 cups of the cheese.
Lightly spray a 9x13 inch baking dish with cooking spray and spread about 1 1/2 cups of enchilada sauce at the bottom.
Generously fill tortillas with the mixture, then roll up and place seam side down. Cover with remaining sauce and the last cup of cheese.
Bake (uncovered) at 375° F for 20 minutes.
