Preheat grill to medium heat. In a large bowl combine all meatball ingredients; it’s easiest to mix together by hand. Roll mixture into 12-15 roughly 1.5 inch balls.
Lightly grease grill and place meatballs in center about 1 inch apart. Cook 10-15 minutes, rotating as needed. Meatballs should reach an internal temperature of at least 165° F and have browned grill marks on outside. Remove from grill and serve with both sauces.
Cucumber Mint Sauce
Place shredded cucumber in a strainer and press down firmly to remove liquid. Pulse cucumber and remaining ingredients in a food processor until well blended, scraping sides as necessary.
