Preheat a saute pan over high heat, add the olive oil and allow to come up to a high temperature. Add the onions and cook until slightly softened, 1 to 2 minutes. Stir in the sausage and red bell peppers, making sure to move the pan around and to continue stirring for even cooking. Cook 1 to 2 minutes. Stir in the mushrooms and broccoli and cook 1 to 2 minutes. Stir in the chopped garlic and cook for 3 to 4 minutes, stirring constantly. (The garlic should take on a golden color, but be sure to not let it burn.) Stir in the chopped chicken and cook 1 to 2 minutes.
Deglaze the pan by adding the chicken stock. Stir around to coat all the ingredients. Add the pasta to the pan, stir to coat and cook for 1 to 2 minutes. Stir in the cream sprinkle in the cheese and cook 2 to 3 minutes. Stir in the parsley and spinach. Remove the pasta from the heat.
Pour the pasta onto a plate, top with the tomatoes and more cheese, if desired.
