Teriyaki Chicken Stir-fry

I am new to this blog and am so excited! You guys all have some great recipes:) I have made this recipe many times! We had it last night and I still love it. I only add 1/4 C. soy sauce and whatever veggies I have. It is easy and delicious.

1 pound chicken breasts, cut in strips
2 Tbsp vegetable oil
Salt and pepper to taste
1 cup baby carrots, cut in halves
1 cup fresh broccoli, cut in bite-size pieces
2 celery stalks, cut up
1 cup fresh zucchini, sliced
2 cups plus 1/2 cup water
1/2 cup soy sauce
1/4 cup sugar
2 Tbsp flour
Cooked rice

Directions
Cook vegetables in simmering water until crisp-tender. Cook chicken strips in a separate pan in oil, using salt and pepper to season. When chicken is cooked, add 2 cups water, the sugar and soy sauce. Mix until sugar is dissolved. After both chicken and vegetables are cooked, drain vegetables and transfer them to the chicken and soy sauce mixture. Bring to a boil, then simmer. Take 1/2 cup water, add flour and stir until flour is dissolved. Add to the simmering chicken and vegetable mixture. Simmer and stir occasionally for 5-10 minutes. Serve over rice.
