Steak Pizzaiola

This is a wonderful dish, low fat with lots of veggies, which I love. :)  I served ours with a simple, yet delicious foccacia bread.  They were amazing together.  Enjoy!
-1 1/4 lbs boneless sirloin steak, about 1 inch thick
-2 Tbs extra virgin olive oil
-4 cloves garlic, minced
-1 large onion, peeled and thinly sliced
-1 red bell pepper, thinly sliced
-1 yellow bell pepper, thinly sliced
-4 Tbs jarred pepperoncini, deli sliced, drained
-15 oz crushed tomatoes
-1/2 tsp dried oregano
-3/4 cup water
- a pinch of red pepper flakes
Sprinkle the steak with salt and both sides. 
Heat the oil in large skillet.  Add the steak and quickly brown on both sides (about 2 minutes per side).  Remove onto a plate and set aside.
To the same skillet add the garlic.  Cook for 1 minute.  Add the onion and peppers.  Stir occasionally and cook for about 4 minutes.  Add the pepperoncini, tomatoes, oregano, water and red pepper flakes.  Give it a good stir.  Once it starts simmering, nestle the steak in the sauce.  Simmer, turning the steak once, until medium well (about 7 minutes).  Transfer the steak to a cutting board and let it rest for 5 minutes.  Continue simmering the sauce until thickened, for about 3 more minutes.
Slice the steak thinly and divide among the plates.  Add the sauce with all the veggies.  Serve with foccacia.  Enjoy!
