Step 1: Prepare the Chicken - Place the chicken into your crockpot. No need to cut it up yet; it will shred as it cooks.
Step 2: Sauté the Aromatics - In a skillet, sauté the onion and garlic until translucent and fragrant.
Step 3: Combine the Spices - Sprinkle in the chili powder, oregano, smoked paprika, thyme, allspice, and crushed red pepper flakes. Stir well.
Step 4: Assemble the Chili - Pour the onion and spice mixture over the chicken. Add tomato paste, chicken broth, balsamic vinegar, bay leaf, and season with salt and pepper.
Step 5: Add the Vegetables - Incorporate the chopped broccoli rabe, roasted red peppers, and cannellini beans.
Step 6: Cook - Set crockpot to low for 6-8 hours or high for 4-5 hours.
Step 7: Shred the Chicken - Remove chicken, shred, and return to the pot. Stir to combine.
Step 8: Serve - Ladle chili into bowls and top with parmesan cheese and chopped parsley. Enjoy!
