Green Seed Vegan's all-veggie Dirty Burque burger is so good, we'll put it up against a meat-based burger any day of the week. It's hard to miss the meat, in fact, when there's so much deliciousness between the buns: The patty is mostly buckwheat, a pseudo-cereal that's gluten-free, high in protein and made from scratch. It's studded with colorful chunks of vegetables, from orange bell peppers to green flares of bright cilantro. On top you'll find buttery slices of avocado, peppery arugula, raw white onion, a tangy spread of egg-free mayonnaise and a New Mexican-style green chile sauce that's tart and slightly hot.
