Prepare the Base: Start by placing the boneless, skinless chicken breasts at the bottom of your slow cooker, spreading them out evenly for consistent cooking.
Layer the Ingredients: Pour the rinsed black beans over the chicken, ensuring they're spread out. Next, add the canned diced tomatoes with their juices, followed by layering the sliced red bell pepper and onion on top of the chicken and beans.
Mix the Spices: In a separate small bowl, combine the minced garlic, ground cumin, chili powder, paprika, salt, and pepper. Stir until the spices are well blended. Sprinkle this mixture evenly over the layers in the slow cooker.
Cook to Perfection: Secure the lid on the slow cooker. Cook on low for 6 to 8 hours, or for a quicker option, on high for 3 to 4 hours. The chicken should be tender and easily shreddable when ready.
Shred the Chicken: Once cooked, use two forks to shred the chicken directly in the slow cooker. Mix it well with the black beans, tomatoes, and peppers to combine all the flavors.
Assemble and Serve: Warm the whole wheat tortillas until pliable. Spoon a generous amount of the warm chicken mixture onto each tortilla.
Garnish and Enjoy: Top with freshly chopped cilantro and squeeze a wedge of lime over the filling before folding or rolling the tortillas. Enjoy your delicious and healthy tacos!
Notes
Consider serving the tacos on a beautiful platter, with extra lime wedges and a small bowl of cilantro on the side for guests to customize their flavors!
