Michael Symon's Salisbury Steaks

So I found this recipe in Michael Symon's 5 in 5 cookbook, and it was easy and delicious, like everything out of that cookbook.  If you notice though, that picture looks like Salisbury mess, not Salisbury steaks :).  While it's not beautiful because my steaks fell apart, it still tastes great.  Each serving for 6 servings was 296 calories, because we used really lean hamburger, and we all really enjoyed this, giving it a 9.  I let everything cook longer than the recipe says, because I like my onions soft, but it is up to you.  Here's what I did:

2 T cornstarch
2 c beef broth
1 lb ground beef
1/4 c bread crumbs
1 egg
1/2 c plus 3 T tomato sauce
4 T Worcestershire sauce, divided
salt and pepper
3 T olive oil
1 large onion, thinly sliced

Whisk together the cornstarch and 1/4 c beef broth.
Put a large skillet over medium heat.
Combine the beef, bread crumbs, 3 T tomato sauce, 3 T Worcestershire sauce, 1 t salt, and 1/2 t pepper.  Mix thoroughly and season well with salt and pepper.
Add the olive oil to the pan, then place the beef in the pan.  Cook, then move the beef to the side when mostly browned.  Add the onion, and season it with salt and pepper.  When the beef is fully browned, move it to a plate, and add the beef broth, corn starch slurry, tomato sauce, and 1 T Worcestershire sauce to the pan, whisking well.  Season with salt and pepper as needed.  Return the beef to the pan and let the sauce thicken.  Serve with rice or potatoes or noodles.
