Pre-heat oven to 375 degrees. Cut spaghetti squash in half length-wise and scoop out seeds. Rub cut sides of spaghetti squash with olive oil and season with 1/2 tsp Flavor God seasoning.
Place spaghetti squash on a lined baking sheet with cut side up. Bake for 40-45 minutes or until the flesh of the squash flakes easily with a fork. Set aside to cool.
Add ground turkey, sausage, breadcrumbs, and egg whites to a bowl. Mix with your hands until just combined, then roll into 1 to 1 1/2 inch meatballs. Set aside.
Heat a cast iron skillet (or other oven safe skillet) over medium-high heat and add olive oil. Add minced garlic, mirepoix, and pepper rings and sauté until fragrant. Add crushed tomatoes and tomato paste and stir, then add basil and stir again.
Remove skillet from heat and drop meatballs into sauce. Cover meatballs with sauce and bake for 20-25 minutes or until meatballs are cooked through.
Serve meatballs and sauce on top of spaghetti squash.
