In a large bowl, combine ground turkey, ground pork, mozzarella, 4 cloves of minced garlic, Italian seasoning, red crushed chili pepper flakes, crumbled bouillon cube, salt, black pepper, and chopped parsley. Mix well and combine.

Roll approximately 12 meatballs out of the mixture in your hands and set them aside.

Place a large skillet over medium-high heat and add in 2 tbsp of butter. Add in the meatballs and cook for 8-10 minutes on all sides. You want to make sure the meatballs brown up and are cooked through, so keep on flipping them around. Once cooked, remove them from the skillet and set them aside.

Now, add the remaining 1 tbsp of butter into the skillet, squeeze in the lemon juice, Sriracha sauce, and 2 minced garlic cloves. Give everything a mix before adding in the spiralized zucchini.

Cook zucchini noodles for 3-4 minutes, stirring regularly until they're done. Salt and pepper to taste, and push the zucchini noodles to the side of the skillet.

Add the meatballs back into the skillet, reheat them for a couple of minutes. Baste them with the liquids from the pan and serve immediately.
