Ingredients

2 teaspoons olive oil
1/2 red or yellow bell pepper, seeded and finely chopped
1/2 onion, finely chopped
2 tablespoons minced carrot
2 tablespoons minced celery
2 garlic cloves, minced
2 cups finely chopped mushrooms
3/4 pound lean ground beef (at least 90 percent lean)
1 tablespoon steak sauce
Salt and freshly ground pepper to taste

Directions

In a medium nonstick skillet, heat the oil. Saute the bell pepper, onion, carrot, celery and garlic until the onion is translucent, 8 to 10 minutes. Add the mushrooms; saute until the mushrooms brown and the liquid evaporates, about 8 minutes. Cool to room temperature.

Spray the grill rack with nonstick cooking spray; preheat the grill. In a medium bowl, combine the mushroom mixture, beef, steak sauce, salt and pepper. Form into 4 hamburgers. Grill 3 inches from the heat, 5 to 7 minutes each side. Makes 4 servings.
