Pepper Steak

I received a really nice Dutch oven for Christmas and I've been looking for the perfect recipe to try it out. This was it. Mmmmm...so good!

2-3 Tbsp vegetable oil
1 1/2 lbs top sirloin steak, trimmed of fat and cut into bite size strips
1 cup water
1 medium onion, sliced
1/2 tsp garlic salt
1/4 tsp ground ginger
1 red bell pepper, cut into bite size strips
1 yellow bell pepper, cut into bite size strips
2 Tbsp soy sauce
2 1/2 tsp sugar
1 Tbsp cornstarch

Heat the oil in a large, heavy pot or Dutch oven. Add the meat and brown for 5 minutes. Stir in the water, onion, garlic salt, and ginger. Bring to a boil, cover, reduce the heat, and simmer for 10 minutes. Add the peppers. Cover and simmer for 5 more minutes. Meanwhile, stir together the soy sauce, sugar, and cornstarch. Pour this into the pot and stir until the liquid thickens and comes to a boil. Simmer 5-10 minutes longer. Serve over rice.
