Start your BBQ's, because the best Grillable Veggie Burger with Diner Sauce is here! Loads of flavour and texture makes these hearty burgers a knock-out for both vegans and meat eaters!
In a small frying pan, heat the olive oil on medium heat and add the onion. Cook, stirring, for 3-4 minutes or until the onions start to soften and turn golden. Add in the garlic. Cook for an additional 1-2 minutes or until the garlic becomes fragrant. Remove from the heat.
In a food processor, pulse the mushrooms until they are small pieces but not a paste. Transfer to a large bowl and set aside.
In the food processor again, pulse the walnuts until they are coarse crumbs. Add in the black beans, cilantro, nutritional yeast, soy sauce, cumin, chilli powder and pepper. Add the walnut mixture to the mushrooms along with the oats, panko or bread crumbs and cooked onions. Stir together to combine, cover and refrigerate for at least 30 minutes.
Shape into patties (we used a size 8 scoop which was perfect!) and cook in a frying pan with a bit of oil until crisp on each side, about 2-3 minutes a side or grill on the barbecue (brush the grill with a bit of oil first). Serve with your favourite burger toppings and enjoy!
