Preheat oven to 400 degrees.
Combine beans, corn, cumin, chili powder, most of the sliced green onion (reserve a small handful for garnish), pepper jack cheese, ½ a cup of enchilada sauce, and salt and pepper in a large bowl.
Pour 1 cup of enchilada sauce into the bottom of a baking dish.
Fill tortilla with about ⅓ a cup filling, roll up enchiladas, and place them seam-side down in the baking dish.
Continue with the remaining tortillas until they are filled.
Pour remaining 1.5 cups of sauce over enchiladas and top with cheddar cheese.
Cover with foil and bake for 20 minutes or until the cheese is melted and the sauce is bubbly.
Garnish with green onion, cilantro, queso fresco, and serve with sour cream and blender salsa.
