While olive oil warms in the pan, pound chicken breasts between saran wrap with a meat mallet (this helps make the chicken tender).
Sprinkle the chicken with salt and pepper.
Once the oil in the pan is hot, sear the chicken for 6-7 minutes. Flip and sear for an additional 5 minutes.
Once the chicken is cooked, remove from the pan and set aside on a plate.
Add the onions and garlic to the pan and cook for 2-3 minutes until they start to soften.
Once onions and garlic have cooked, add mushrooms and spices to the pan. Stir together and cook for an additional 5 minutes until the mushrooms start to soften.
Once mushrooms have cooked, add red wine and peppers. Cook over medium heat for 5 minutes. Add chicken stock and crushed tomatoes. Stir to combine.
Add cooked chicken back to the pot. Stir to combine, cover and cook on low to medium heat for 20-30 minutes, stirring occasionally.
While the chicken cooks, boil water for your pasta according to directions.
Drain the pasta well and add to the pot. Stir together with sauce/chicken & enjoy!
