As my vegetarian Meatwave constituency continues to grow and I'm finding myself crafting more and more meatless recipes, I'm becoming more in tune to what I personally like about veggie recipes, and that's not trying to make something taste like meat, but make it taste like what it is—vegetables.
The Sparrow bakes their burgers before they hit the flat top, so I tried to replicate that on the grill using a two-zone fire, where all the coals are on one side of the charcoal grate, and first roasting the burgers before searing them.
The sweet and spicy sauce and lightly bitter bite of the frisée were also great compliments to the flavors going on in the patty, while the pita felt like a fitting change of pace from a bun—further reminding you this wasn't trying to be a fake version of what's mostly commonly a beef dish, but something unique and true to its own make-up, which is what makes me personally love this veggie burger more than most.
Place mashed potatoes, mushrooms, carrot, zucchini, barley, brown rice, corn, peas, bread crumbs, egg, scallions, bell pepper, salt, and pepper in a large bowl and, using your hands, mix ingredients until well combined.
