Ingredients
- 1-1/2 cups old-fashioned oats
- 6 medium fresh mushrooms, stems removed
- 1 shallot, quartered
- 1 small carrot, grated
- 3 garlic cloves, minced
- 1 cup cooked lentils
- 1 tablespoon maple syrup
- 1 tablespoon tomato paste
- 1 tablespoon spicy brown mustard
- 1 teaspoon kosher salt
- 1/2 teaspoon dried marjoram
- 1/4 teaspoon pepper
- 1/4 teaspoon crushed red pepper flakes
- 1/8 teaspoon garlic powder
- 2 tablespoons olive oil
- 2 tablespoons mayonnaise
- 2 tablespoons prepared mustard
- 2 tablespoons ketchup
- 6 hamburger buns, split
- optional toppings: fresh arugula, sliced tomato and sliced red onion
Directions
- In a food processor combine the first 5 ingredients; pulse until combined and shallot is chopped. Add lentils, maple syrup, tomato paste, spicy brown mustard, salt, marjoram, pepper, red pepper flakes and garlic powder. Pulse until combined, but not pasty (mixture should appear crumbly like ground meat). Shape into six 3-in. patties.
- In a large nonstick skillet, heat oil over medium heat. Cook patties until golden brown, 2-3 minutes, turning once.
- In a small bowl, combine mayonnaise, mustard and ketchup. Serve patties on buns with mayonnaise mixture and toppings as desired.
