Heat the oil in a medium pot over medium heat. Add the ground turkey and sauté until browned and cooked through.
Add all the carrots, onion, celery, and garlic mixture and cook until the onions are soft, about 3 to 4 minutes. Stir frequently.
Add the tomato paste and crushed tomatoes. Cook until the sauce starts to simmer.
Stir in the crushed red pepper, salt, and pepper. Turn the heat to low and simmer for another 30 minutes until the sauce thickens.
Remove the pot from the heat and stir in the basil.
Serve with whole wheat pasta or whole grain polenta.
