Knott notes, "While frozen options are very convenient, sodium can add up quickly." A good rule of thumb is to aim for less than 400 milligrams of sodium per burger (see all our tips for buying the healthiest veggie burgers). Whether you're making your own or using store-bought (no shame!), look for higher protein options, especially those made with beans, lentils, tofu or other soy products, to stay satisfied for hours. Beyond the traditional bun with your favorite toppings, you can add veggie burgers to grain bowls, salads or wrap them in butter leaf lettuce. Get creative with your toppings, too! Try pesto or guacamole for healthy fats that add a ton of flavor.
