If there’s one Nutrisystem menu item that should be a staple in your pantry, it’s our ready-to-go Tuna Salad. This perfectly seasoned lunchtime classic takes the meal prep out of your midday meal, so you can forget about opening cans, measuring ingredients, mixing and taste testing. Let Nutrisystem do the cooking for you with generous chunks of light tuna blended with mayonnaise, onions, pickles and water chestnuts. Of course, this lightened up Tuna Salad is delicious all on its own. However, wait until you try it piled high onto sourdough bread and covered in provolone cheese. This Open-Faced Tuna Melt recipe takes our popular Tuna Salad to the next level.
