Prepare the Teriyaki Sauce: In a medium bowl, add the soy sauce, water, brown sugar, seasoned rice vinegar, ginger and garlic. Stir to combine and set aside while you sauté the chickpeas.
Pan Fry the Chickpeas: Heat the oil in a large sauté pan over medium-high heat. Add the chickpeas and sprinkle the onion powder, garlic powder and salt on top, then stir and pan fry for 5-7 minutes, until a little golden brown and crispy.
Add Teriyaki Sauce and Thicken: Stir the teriyaki sauce once more in the bowl before pouring it into the pan with the chickpeas. Bring to a simmer and cook for 1-2 minutes. In a small bowl, combine the cornstarch and water into a slurry, then pour into the pan and stir constantly, to thicken the sauce.
Make Bowls with Toppings of Choice: Serve teriyaki chickpeas over cooked rice with steamed broccoli and any other ingredients you like, such as edamame, mango, chopped green onions and sesame seeds. Enjoy!
