Corn tortillas rolled with melting cheese and bathed in a robust red or green chile sauce. These vegetarian enchiladas make a quick, satisfying family dinner with minimal preparation.
Preheat your oven to 375°F. Lightly oil a 9x13-inch baking dish to prevent sticking.
Heat the vegetable oil in a skillet over medium heat. Briefly warm each corn tortilla for 10-15 seconds per side to soften.
Mix Monterey Jack and Cheddar cheese with chopped onion in a bowl for the filling.
Fill each tortilla with roughly 1/4 cup of the cheese-onion mixture, roll tightly, and arrange seam-side down in the prepared baking dish.
Pour the red enchilada sauce evenly over all the tortillas, covering them fully. Sprinkle with salt and cover with foil. Bake for 20 minutes, then uncover and bake for another 5 minutes until the cheese is melted and bubbly.
