Heat 2 tablespoon oil in a nonstick pot over medium-high heat. Add chicken and 1.5 tablespoon taco seasoning and mix everything together.
Cook until chicken is golden brown.
Remove to a plate and keep aside. I shredded it but you you don't have to.
In the same pot, heat remaining 2 tablespoon oil.
Add onion, peppers, garlic, remaining 1.5 tablespoon taco seasoning and mix everything together.
Cook until veggies are firm but tender and slightly charred.
Remove these vegetables to the plate with the chicken. Keep aside.
In the same pot, add broth, heavy cream, diced tomatoes, pasta, salt, pepper and stir everything together.
Bring to a boil.
Cover and cook on medium-low heat for about 12-15 minutes, stirring often.
Then, mix in chicken and vegetables and cook, uncovered for another 5 minutes.
If the pasta is looking too watery, cook on high for a few additional minutes until all the excess liquid is absorbed into the pasta. If the pasta is still not cooked through and pasta is becoming dry, add a little more broth or water and continue cooking, uncovered for a few additional minutes.
Garnish with toppings of your choice and enjoy.
