Cheesy Turkey and Cauliflower Rice Taco Skillet

Heat the oil in a large skillet over medium high heat. Add the onions and sauté a few minutes until they start to soften. Add the garlic and cook another minute until fragrant. Add the ground turkey and season it with a pinch of salt and pepper. Cook the turkey until browned, breaking it up with a spatula as it cooks.
Add the tomato paste and mix it into the turkey. Cook 1-2 minutes and then add the fire roasted tomatoes, water, chili powder, cumin, 1 teaspoon salt, and ¼ teaspoon pepper. Stir to combine. Stir in the frozen riced cauliflower and corn (no need to defrost them). Cook 6-7 minutes until the vegetables are cooked. Stir in the black beans and about half of the grated cheese. Simmer another minute until cheese is melted.
Sprinkle the remaining half of the cheese evenly over the skillet and cover with a lid for a minute until melted. Uncover and garnish with avocado slices and cilantro. Serve with sour cream or Greek yogurt, if desired.
