1 1/2 lbs flank steak
1/4 cup cornstarch
2 tbsp oil
1/2 tsp garlic, minced
3/4 cup soy sauce
3/4 cup water
3/4 cup brown sugar
1 tbsp sweet chili sauce
1 cup grated carrots
small onion, chopped (they garnished with green onions, I just tossed in some onion)
White rice, cooked
1 pkg frozen broccoli (I use my own)
Cut flank steak into streaks. Coat with cornstarch (they did this is a ziploc, I did this in a bowl). Add rest of ingredients (minus rice and broccoli) to crock pot. Add in coated steak and mix. Cook on low for 4-5 hours. Add in frozen broccoli in last 30 minutes.
Serve over rice.
