Combine crushed tomatoes and Mama Mia Marinara Sauce Mix in a small pot over low heat. Let simmer 20-25 minutes. Heat meatballs according to package directions.
When sauce and meatballs are almost done, place spiralized zucchini in a casserole dish with lid. Place in microwave, covered, and cook on HIGH for approximately 4 minutes, until zoodles reach desired tenderness.
To serve, top cooked zoodles with meatballs and marinara. Serve with Italian garlic bread, if desired.
Tip: Instead of frozen meatballs, make your own with this recipe for Italian Garlic Turkey Meatballs.
