Beef and Mushroom Sloppy Joes

This is a super easy, filling and good for your recipe courtesy of Cooking Light.  A caveat though - the magazine claims this makes four sandwiches.  Maybe I make wimpy sandwiches, but B and I can get six to eight good size sandwiches out of each batch of this quick, healthy recipe.

Ingredients

1 tablespoon olive oil
12 ounces ground sirloin
2 (8-ounce) packages presliced cremini mushrooms
1 cup chopped onion
3 garlic cloves, minced
1/2 cup tomato paste
1 tablespoon minced fresh oregano
2 tablespoons red wine vinegar
2 tablespoons Worcestershire sauce
1 tablespoon molasses
1/4 teaspoon salt
3/4 teaspoon fresh cracked pepper
Hot sauce to taste
4 hamburger buns, toasted in the oven

Heat a large nonstick skillet over medium-high heat. Add oil; swirl to coat. Add beef; cook for 4 minutes or until browned, stirring to crumble. While beef cooks, place mushrooms in a food processor; pulse 10 times or until finely chopped. Add mushrooms, onion, and garlic to pan; cook for 3 minutes or until onion is tender. Add tomato paste and next 5 ingredients (through salt) to pan; cook 5 minutes or until mushrooms are tender and liquid evaporates. Stir in pepper and hot sauce. Spoon about the  beef mixture on bottom half of each bun; top with top halves of buns.
