Whether you’re trying to save your pennies or joining the Meatless Monday movement, adding flaxseeds to a vegetarian burger recipe is a great way to create a meaty flavor (umami). Flaxseeds help bind the ingredients together, so ditch the breadcrumbs and blend in 1/4 cup of ground flaxseeds instead. Bonus: flaxseeds are gluten-free! Total Time Prep: 25 min. Grill: 10 min.
