"If we had to submit one vegan burger to meat-eaters as proof that the impossible can be done, we would nominate a double Mission burger with cheese, special sauce, and grilled onions. It somehow defies the fundamental laws of burger physics—there’s a thick crust on a couple of thin smashed patties topped with incredibly melty cheese, and it does it all without using any animal products. This sorcery takes place on the patio of Zed’s—a New Zealand-style ice cream shop in East Austin—which means you already have dessert figured out after your meal. There’s also a brick-and-mortar location on South Congress, but you came to this guide for food trucks, not sit-down spots. " - nicolai mccrary
