In a large heavy pan heat 2 tbsp oil over high heat until oil is hot. Add chicken and half the seasoning, tossing to coat well. Spread chicken in a single layer and let cook undisturbed for about 1 min, or until browned on bottom side. Flip chicken over and repeat until both sides are browned. Remove chicken to a large bowl and set aside.
Add remaining 2 tbsp oil to the pan over high heat. Once oil is hot, add the onions, bell peppers, and garlic, along with remaining half of seasoning. Stir well to coat; stir often and cook until veggies are tender, 2 min.
Add broth, tomatoes with all its juices, and dry pasta to the same pan. Bring liquid to a boil and immediately reduce to a low boil. Cover and let cook for 15 min. until pasta is cooked. Liquid should be mostly absorbed. When pasta is cooked, add the chicken back to the same pan. Add freshly ground black pepper to taste. Stir to combine and heat through.
