INGREDIENTS
- 1 lb chicken breast, cooked and shredded into bite-sized pieces
- 2 tablespoons olive oil
- 1 red bell pepper, chopped
- 1 red onion, chopped
- 2 teaspoons kosher salt
- 1 teaspoon black pepper
- 1 tablespoon chili powder

- 1/4 cup heavy cream
- 1 cup shredded pepper jack cheese

INSTRUCTIONS
- Preheat your oven to 350°F.
- Heat the olive oil in a large pan over medium heat (a 9″ oven-safe skillet works great for a one-pan meal). Once hot, add the chopped red bell pepper, red onion, salt, and black pepper. Sauté until softened.
- Stir in the chili powder, cumin, and dried oregano, cooking for about 2 minutes until fragrant.
- Remove the pan from heat and mix in the sour cream, salsa, and shredded chicken. Stir until everything is well combined.
- Transfer the mixture to an 8×8 casserole dish if not using an oven-safe skillet.
- Drizzle the heavy cream evenly over the top, then sprinkle with shredded cheese.
- Bake for 30 minutes or until heated through and the cheese is golden brown.
- Garnish with fresh cilantro and serve warm. Enjoy!
