Preheat oven to 350°. Place meatballs in a baking dish (appx. 9" x 9") and cover with masala sauce. Place in oven and let cook for about 20-30 minutes, or until meatballs are heated through and sauce is hot. Alternatively, use a slow cooker to heat meatballs and sauce, about 5-6 hours on low or 2-4 hours on high until heated through. Serve warm alongside a dipping bowl of Mango & Ginger Chutney.
