Ingredients
1 tablespoon olive oil
1/2 cup minced onion
2 garlic cloves, minced
12 ounces portobello mushrooms, shredded or finely chopped
1 (4-ounce) can chopped green chiles, drained
1 tablespoon soy sauce
2/3 cup ketchup
2 teaspoons prepared yellow mustard
1 tablespoon chili powder
1/2 teaspoon liquid smoke
1/2 teaspoon salt
1/4 teaspoon black pepper
4 toasted burger rolls
Preparation
In a large saucepan, heat the oil over medium heat. Add the onion, cover, and cook until softened, 4 minutes. Add the garlic and cook 30 seconds longer. Stir in the mushrooms, chiles, and soy sauce and cook for 2 to 3 minutes to lightly brown. Stir in the ketchup, mustard, chili powder, liquid smoke, salt, and pepper. Mix well, adding a little water if the mixture is too dry. Simmer for 5 minutes to blend flavors. When ready to serve, spoon the mixture onto the rolls and serve hot.
