Before you start cooking, get all your ingredients ready. Cut the veggies into bite-sized pieces (keep the broccoli pieces small so they cook quickly). Slice the chicken into 1-inch pieces and set aside.

In a medium bowl, whisk together all the sauce ingredients - chicken broth, mirin, soy sauce, vinegar, brown sugar, cornstarch, grated ginger, and minced garlic. Set this aside for later.

Put your chicken pieces in a bowl and sprinkle with garlic powder and pepper. Stir to coat all the pieces. Add the cornstarch and toss until the chicken is evenly coated.

Heat 2 tablespoons of olive oil in a deep skillet over medium-high heat. Once hot, add half the chicken, shaking off excess cornstarch before adding to the pan. Cook for about 4 minutes, then flip and cook another 3-4 minutes until browned and cooked through. Transfer to a plate.

Add the remaining tablespoon of oil to the pan and cook the second batch of chicken the same way. Once done, transfer to the plate with the first batch.

If your pan is dry, add a small splash (about a teaspoon) of olive oil. Add the onions and cook for 1 minute, stirring occasionally. Add the broccoli and bell peppers, and cook for about 3 minutes, stirring often, until the veggies are tender-crisp. Cook a bit longer if you prefer softer vegetables.

Return the cooked chicken to the pan with the vegetables. Give your sauce a quick whisk and pour it in. Let everything bubble together until the sauce thickens (usually less than a minute), stirring constantly so all ingredients get coated. Remove from heat and serve immediately.
