Ingredients

• 1 1/2 lbs flank steak – cut across the grain into 1/4-inch strips
• 3 tbsp cornstarch
• 2 tbsp vegetable oil

For the sauce

• 1 tbsp vegetable oil
• 3 cloves garlic – minced
• 1/4 tsp ginger root – freshly grated (or ginger paste)
• 1/2 cup water
• 1/3 cup hoisin sauce
• 1/3 cup low-sodium soy sauce
• 2 tbsp brown sugar
• 2 tbsp rice wine vinegar
• 1/2 tsp crushed chili paste or chili flakes

Vegetables

• 1/2 cup water chestnuts – sliced
• 1 cup bell peppers – chopped
• 1 head broccoli – cut into florets and lightly steamed
• 3 green onions – cut into 1-inch pieces

Instructions

• Toss the strips of beef in the corn starch and let them sit on the cutting board for 15 minutes.
• Meanwhile, prepare the sauce. In a small saucepan set over medium heat add the vegetable oil. 
• When the oil is hot, lightly sauté the garlic for a minute, then add the ginger and cook for 30 seconds. Pour the remaining ingredients in the pan and simmer for 5 minutes or until the sauce begins to reduce or thicken. Keep warm while preparing the rest of the ingredients.
• In a large skillet set over medium-high heat, add the 2 tablespoons of vegetable oil. When the oil is hot, quickly stir-fry the beef in 2-3 batches. You want it to be nice and crisp on the outsides, but not cooked throughout. Transfer cooked beef to a plate. If the pan has a lot of oil in it, remove all but 1 tablespoon of oil.
• Add the vegetables and sauté for 2-3 minutes before returning the beef to the skillet. Add the sauce, stir, and allow everything to cook for an additional 2 minutes before removing from the heat. Serve immediately.
