Aren’t those Lean Cuisines dinners supposed to be a healthy alternative? Nestle Prepared Food Co. announced Tuesday a voluntary recall of frozen spaghetti and meatball dinner after reports of red plastic being found in the meatballs. The recall applies to packages of the dinners manufactured during a one-hour period in October 2010 with the production code 0298595519 P, a release by the company said. The company said no other products were affected by the possible contamination. Nestle advised customers to read the “proof of purchase” panel to find out the product code before contacting them.
