Step-By-Step Directions
Grill the Chicken

- Pat the chicken breasts dry. Melt the butter, inject or brush it into and over the chicken, then coat with Italian rub.
- Place the chicken on the grill and cook with the lid closed.
- Grill until the internal temperature reaches 165°F, checking with a digital meat thermometer.
- Remove the chicken from the grill and let it rest for about 5 minutes, then thinly slice. Reserve half of the cooked chicken for another meal if desired.
Prepare the Pasta and Sauce
- Cook the spaghetti according to package directions, then drain.
- In a pan, heat olive oil over medium heat. Add the sliced bell peppers, diced onion and shredded carrot. Cook, stirring often, until the vegetables soften.
- Stir in the tomato sauce, butter, brown sugar, granulated garlic, dried basil, dried thyme, dried oregano, kosher salt and black pepper.
- Bring the sauce to heat through, then reduce to a simmer and keep warm for a few minutes to let the flavors meld.
- Toss the sauce with the cooked spaghetti so the pasta is well coated.
Serve

Place sliced grilled chicken over the sauced spaghetti and garnish with fresh basil if desired. Serve immediately with a side salad and garlic bread or biscuits for a complete family meal.
