Salisbury Steak

Here's a real easy tasty Salisbury steak dinner.

Ingredients
1/3 cup grated onion, divided
1/2 teaspoon black pepper
1/4 teaspoon salt
2 garlic cloves, minced
1 pound ground sirloin, we used extra lean ground beef.
Cooking spray
1 tablespoon butter
8 ounces cremini mushrooms, quartered. or you can use any kind of mushrooms.
1/3 cup dry red wine
1 1/4 cups fat-free, lower-sodium beef broth
1 tablespoon all-purpose flour
1 teaspoon red wine vinegar

Preparation
1. Combine 1/4 cup onion, pepper, salt, garlic, and beef. Shape into 4 (1/2-inch-thick) patties. Heat a skillet over medium-high heat. Coat with cooking spray.
Add patties; cook 3 minutes on each side or until browned.
2. Melt butter in pan. Add mushrooms; saute 4 minutes.
Stir in wine and remaining onion; cook 2 minutes.
Combine broth and flour; add to pan, and bring to a boil. Cook 5 minutes or until thick.
Add patties and vinegar to pan; cook 2 minutes.

Now we served it with boxed mashed potatoes instead of real mashed potatoes cause we were lazy.
And we had squash.
I forgot to get a pic before we ate, so I got this one off the Cooking Light website.
But it was good!
