Making a quick bag lunch for kids isn’t hard, but making a lunch that will nourish and be enjoyed by children can be tricky. The North American Meat Institute, a contractor to the Beef Checkoff, has created a new “Beef Up the Lunch Box” series of lunch recipes and menus that incorporate prepared beef favorites likes summer sausage, roast beef, pastrami and corned beef into nutritious and delicious recipes that kids will eat and enjoy and that will help keep hunger at bay during the day.
