Beef and Brocoli

My kids LOVE a good stir fry, so tonight we had beef and broccoli. Ingredients:
Top Sirloin (however much you want)
Brocoli (however much you want)
Carrots, optional
Onion, optional

Marinade:
2 tablespoon rice vinegar
2 teaspoon sugar
2 teaspoon soy sauce
2 tablespoon water
2 tablespoon cornstarch

Thinly slice the steak and marinate in the marinade mixture for at least 30 minutes prior to cooking. Heat oil in a skillet and cook until meat changes color, but still has slight pink in the middle (1 to 2 minutes). Don't over cook. Remove from pan and drain on paper towel.

To cook Vegetables:
1/2 cup water (more if you use carrots and onion)
1/4 tsp. salt
1/2 tsp. sugar

Sauce:
4 tablespoons oyster sauce
2 tablespoon light soy sauce
2 tablespoon dark soy sauce
2 tablespoon water

Mix sauce in a small bowl and pour over vegetables and meat and heat through right before serving.

Thickener:
2 teaspoon cornstarch mixed with 1 tablespoon water
1 pound fresh broccoli
1 TBSP. minced garlic

To Cook Broccoli:
1/2 cup water
1/4 teaspoon salt, or to taste
1/2 teaspoon sugar, or to taste

Saute the garlic in a little olive oil until it smells yummy. Add brocoli and saute for a few minutes. Add water, salt and sugar and cover and bring to a boil and let simmer for 4 to 5 minutes, leaving the vegetables slightly crunchy. Add meat and sauce and serve over rice.
