In a large skillet heat two tablespoons of olive oil over medium-high heat. Add the garlic, red pepper flake, and coarse black pepper to the pan and cook for 2-3 minutes.
Add in thin strips of chicken breast, and salt, and cook until chicken is fully cooked, 3-4 minutes.
First pour the marinara sauce over the chicken and stir, then add in heavy cream and stir to combine. Let the sauce simmer for about 10 minutes.
Add in the butter and peas and stir until the butter melts.
Mix the cooked pasta into the sauce and garnish with fresh parmesan cheese and a pinch or two of red pepper flakes before serving.
