1 ½ lbs boneless, skinless chicken breasts
1 large onion, sliced
1 (14.5 oz) can diced tomatoes, drained
2 cloves garlic, minced
1 Tbsp chili powder
1 tsp ground cumin
1 tsp paprika
½ tsp dried oregano
Salt and black pepper, to taste
Juice of 1 lime
Fresh cilantro, for garnish
Tortillas and toppings (e.g., sour cream, guacamole, shredded cheese, pico de gallo) for serving
Layer sliced onions and bell peppers at the bottom of your slow cooker. Place chicken breasts on top, then sprinkle with chili powder, cumin, paprika, oregano, garlic, salt, and pepper. Add the drained diced tomatoes and squeeze in lime juice. Cover and cook on low for 6 hours or high for 3 hours. Once tender, shred the chicken with two forks directly in the crockpot, then stir it together with the veggies and juices. Serve spoonfuls of the fajita mixture in warm tortillas, topping with cilantro and other your favorite accompaniments.
