This veggie burger recipe is healthy and deceivingly easy to make. Simply marinate these meaty mushrooms in a sweet-tart vinigrette for a flavorful and low-calorie dish that even carnivores can enjoy.
To make balsamic vinaigrette whisk all ingredients in a medium bowl until incorporated.
In a large, shallow dish, drizzle mushrooms with vinaigrette and marinate for at least 30 minutes (or overnight, covered and refrigerated). Season with salt, pepper, and 1/4 teaspoon olive oil (or just enough to lightly coat surface).
Meanwhile, preheat the grill to medium-high. Add mushrooms and grill for 3 minutes; flip and cook them for another 3 minutes.
To build burgers, place frisée (if using) and a mushroom on each bun bottom. Add onion, avocado, tomato, and a bun top.
