- Enchilada Sauce:
- 3 tablespoons vegetable oil
- 1 tablespoon all-purpose flour
- 2 tablespoons chili powder, or more to taste
- 2 cups chicken stock
- 1 (6 ounce) can tomato paste
- 1 teaspoon dried oregano
- 1 teaspoon ground cumin
- 1/4 teaspoon salt
- Enchiladas:
- cooking spray
- 1 pound ground beef
- 1 teaspoon extra-virgin olive oil
- 1 onion, diced
- 2 (4 ounce) cans fire-roasted diced green chiles
- 1/2 green bell pepper, diced
- 1 (15 ounce) can black beans, rinsed and drained
- 8 low-carb high-fiber tortillas (such as La Tortilla Factory®)
- 1 (8 ounce) package shredded low-fat Mexican cheese blend
- Heat vegetable oil in a saucepan over medium heat. Add flour; cook and stir using a wooden spoon until smooth, 1 to 2 minutes. Mix in chili powder and cook until fragrant, about 30 seconds. Stir in chicken stock, tomato paste, oregano, cumin, and salt; bring to a boil. Reduce heat and simmer enchilada sauce until thickened and smooth, about 15 minutes.
- Preheat oven to 375 degrees F (190 degrees C). Coat the inside of a 9×13-inch baking dish with cooking spray.
- Heat a large skillet over medium-high heat. Cook and stir beef in the hot skillet until browned and crumbly, 5 to 7 minutes; drain and discard grease.
- Heat olive oil in a separate skillet over medium heat; cook and stir onion, green chiles, and green bell pepper until softened, 5 to 10 minutes. Mix in ground beef and black beans. Stir in 1/2 of the enchilada sauce; cook and stir 1 to 2 minutes.
- Spoon beef mixture evenly onto the center of each tortilla and roll tortilla around filling. Place tortillas, seam-side down, in the baking dish. Cover tortillas with remaining enchilada sauce and Mexican cheese blend.
- Bake in the preheated oven until cheese is melted, about 20 minutes.
