Spicy Vegan Sloppy Joes (Food Network Kitchens) Recipe

Directions:

1. Pulse the mushrooms in batches in a food processor until finely chopped. Set aside.
2. Heat the oil in a large nonstick skillet over medium-high heat. Add the onions, 1 tablespoon beer and 1/4 teaspoon salt and cook, stirring frequently, until the onions are lightly browned, about 5 minutes. Add the walnuts and peppers and cook, stirring occasionally, until the peppers are crisp-tender, about 3 minutes. Add the mushrooms, 3/4 teaspoon black pepper and chipotle powder and cook, stirring frequently, until the mushrooms are just cooked through, about 5 minutes.
3. Add the remaining beer, the ketchup, tomato paste and 1/8 teaspoon salt and cook while stirring until the sauce is the consistency that you like, about 2 minutes.
4. Spoon the mixture onto each bun. Serve with toppings if desired.
5. Cook's Note: Some buns are not vegan so check the label to be sure your hamburger buns are dairy and egg free.
