I'm sorry, but hot dogs with mac n' cheese—gluten-free or not—cannot be labeled as a healthy lunch.
Brown Rice Pasta - About 85 percent of the calories in brown rice pasta comes from carbohydrates. You need carbs in your diet to provide energy to all cells. Nathan's All Beef Hot Dogs - Just like carbohydrates, protein also provides 4 calories per gram. Between 10 to 35 percent of your diet should come from protein. When compared to my child's public school cafeteria choices I think this option is very appropriately labeled healthy but Thanks for your comment.
