Add the rice, water, and a large pinch of salt to a small pot. Heat on high to boil, stir well, then cover and turn heat to low. Cook for 15 minutes. Take pot off the heat, but do not remove lid so that rice may continue to steam.
In a saucepan, bring the orange juice, sugar, and soy sauce to a boil. Simmer over moderately high heat until reduced to 1/2 cup, about 15 minutes. Stir in the zest.
In a large pan, heat 1 tablespoon of the oil over medium high heat. Season the shrimp with salt and pepper. Cook half of the shrimp over medium heat, until white throughout, ~3 minutes. Transfer the shrimp to a plate.
To the now-empty pan, add 2 tbs water and heat to medium high. Add the snow peas or snap peas, and stiry fry for about 2 minutes. (If you use the frozen veggies, this step is not needed as you heated them in the microwave)
Return all of the shrimp to the pan with the veggies, add the orange glaze, season with salt and pepper and toss to coat.
Divide the shrimp and veggie mix between serving dishes,,and serve with rice.
