In a large skillet, heat olive oil in pan on high heat. Then add in the ground beef, ground pork and onion. Mix and break up for 5 minutes until browned.
Reduce the heat to medium. Add in the garlic, Italian seasoning, dried basil, and tomato paste. Mix well, then add in the crushed and diced tomatoes. Mix again and reduce heat to medium-low and simmer for 10 minutes with lid on.
While the sauce simmers, spiralize the zucchini.
Once the sauce has cooked for 10 minutes, add the zucchini to the sauce pan. Cover and cook for 3 minutes. Mix well, divide evenly among plates and enjoy.
