Beef with Broccoli

Combine 2 tbsp cornstarch, 2 tbsp water and garlic powder in a bowl and mix until smooth. Add beef and toss until well coated. Stir-fry beef in a large skillet or wok over medium-high heat in 1 tbsp oil until meat is no longer pink, about 10 minutes. Remove meat from skillet and keep warm. Stir-fry broccoli in the remaining oil for about 5 minutes, then return beef to pan. Mix together soy sauce, brown sugar, ginger and remaining 1 tbsp of cornstarch and 1/2 cup water until smooth; add soy mixture to skillet. Cook for 2 minutes, stirring frequently. Serve over rice.
