Mmmmmm...I just love six sisters stuff!  This meal is easy and smells SO good while cooking!  

1 1/2 pounds beef flank steak, cut into stir-fry sized strips (we used a bottom round roast because it was cheaper and it worked great)
1/4 cup cornstarch
2 tablespoons olive oil
1/2 teaspoon minced ginger
2 cloves garlic, minced
3/4 cup soy sauce
3/4 cup water
3/4 cup brown sugar
1/2 cup shredded carrots
3 medium green onions, chopped

Directions:
Spray slow cooker with non-stick cooking spray. Place cornstarch in a bowl. Coat each piece of steak in cornstarch and place in crock pot. Discard any remaining cornstarch. Combine remaining ingredients in a bowl and pour over beef in crock pot. Cook in crockpot on high for 2-3 hours or low for 4-5 hours. Serve over rice, topped with additional sliced green onions.
