Eating Vegan Has Come to the Grill

Anyone who thinks a grill recipe must have meat will be pleasantly surprised by my Vegan Portobello Cheesesteak. Some people might roll their eyes when they hear the word “Vegan,” but this recipe proves it’s not all raw veggies and rabbit foods. With a little creativity, vegan grilling can be just as flavorful as anything else you’d toss on the grill. In fact, with ingredients like soy-sauce-marinated Portobello caps and cashew white cheddar cheese sauce on the table, you’re about to find out how tasty vegan grilling can be.
