Follow these steps to create your delicious Skillet Enchiladas Suizas:

1. Heat the Skillet: In a large skillet, heat the olive oil over medium heat.
2. Sauté Onions and Garlic: Add the diced onion and minced garlic to the skillet. Sauté until the onions are translucent, about 3-4 minutes.
3. Add Chicken and Spices: Stir in the shredded rotisserie chicken, cumin, chili powder, salt, and pepper. Cook for an additional 2 minutes until heated through.
4. Prepare the Tortillas: Warm the corn tortillas in a microwave or on a skillet for easier rolling.
5. Assemble Enchiladas: Spoon some of the chicken mixture onto each tortilla. Roll them up tightly and place them seam-side down in the skillet.
6. Mix the Sauce: In a medium bowl, combine the green enchilada sauce and sour cream.
7. Add Sauce to Enchiladas: Pour the enchilada sauce mixture evenly over the rolled tortillas in the skillet.
8. Top with Cheese: Sprinkle Monterey Jack and cheddar cheese generously over the top.
9. Cover and Simmer: Cover the skillet with a lid and let it simmer for 10-12 minutes, or until the cheese has melted and is bubbly.
10. Garnish and Serve: Remove from heat, garnish with chopped cilantro and sliced jalapeños if desired. Serve hot!

These steps will lead you to a beautifully crafted Skillet Enchiladas Suizas that are deliciously satisfying.
