Bring chicken broth to a boil then add rice, place a lid on top, turn heat down to medium-low, and cook until rice is tender, 40-45 minutes. Alternatively you could use 4-1/2 cups cold, leftover cooked rice.
Meanwhile, combine teriyaki sauce ingredients EXCEPT for the cornstarch and water in a small saucepan or skillet over medium heat then cook until sugar is dissolved, 2-3 minutes. Stir together cornstarch and water in a small dish then drizzle into sauce mixture and simmer until thickened and bubbly, 1-2 minutes. Set aside.
Heat a large, nonstick wok or skillet over medium-high heat then add 1 teaspoon oil. Lightly season the shrimp with garlic salt and pepper then add to wok and stir fry until cooked through, 2 minutes. Remove to plate then set aside.
Heat remaining teaspoon oil in the wok then add corn, peas, and green onions. Stir fry until heated tender, 3-4 minutes, then add rice, cooked shrimp, and teriyaki sauce Toss to combine then serve.
Notes
Fried rice is a great way to use leftovers! Throw in any type of cooked protein or veggies that are in the fridge or freezer.
