Dietitian’s Tip: Aside from adding fibre, vitamins, minerals and antioxidants to meatballs, vegetables add moisture and flavor too. The trick? Finely grate or finely dice the vegetables so they cook through. No one wants a semi-raw chopped bit of onion in a meatball! Kids Cook!* Kids love the rolly-polly step making meatballs BUT give them a one tablespoon measure so they are the same size, not golf ball and tennis ball sizes. Explain they need to be the same size to ensure even cooking.
