Beef and Broccoli Stir Fry

A bowl full of sliced beef. Doesn't matter to me what cut
1 tbsp. oil
2 to 3 cloves garlic, crushed
3/4 c. soy sauce
2 c. beef broth
1 to 2 tbsp. sugar
1 lg. head broccoli, cut up in small pieces
6 to 8 carrots, cut up small or little shoestrings
1 lg. can sliced mushrooms (optional)
3 tbsp. cornstarch & 1 c. water
Rice

*Tip: Cut meat in slices while a little frozen to make it eash but let meat come to room temp before cooking. If you put cold meat in a hot pan it tightens up and gets tough.

Heat oil and garlic in skillet until garlic turns light brown around the edges. Then put in beef immediately and stir until brown. Then add soy sauce, beef broth, sugar and juice from mushrooms. Stir and simmer 15 to 20 minutes. Add cut up broccoli, carrots, and mushrooms. Stir into beef mixture. Cover and simmer 5 minutes. Stir once or twice. Take 1 cup water and stir in cornstarch. Add to stir fry to thicken. Serve over rice.
