Step 1: Prepare the Rice. Begin by cooking the rice according to package instructions. If using a rice cooker, simply add the rice and water and let it do the work. Fluff it with a fork once it's done.
Step 2: Coat the Chicken. In a mixing bowl, toss the bite-sized chicken pieces with cornstarch until evenly coated. This will give the chicken a crispy texture when cooked.
Step 3: Cook the Chicken. Heat olive oil in a large skillet or wok over medium-high heat. Add the cornstarch-coated chicken pieces and sauté for about 5-7 minutes, or until they are golden brown and cooked through. Remove the chicken from the skillet and set aside.
Step 4: Sauté the Green Beans. In the same skillet, add the fresh green beans and cook for about 3-4 minutes until they are tender but still crisp.
Step 5: Prepare the Sauce. In a small bowl, whisk together the brown sugar, minced garlic, grated ginger, soy sauce, sriracha, and water. Pour this mixture into the skillet with the cooked green beans.
Step 6: Combine Everything. Return the cooked chicken to the skillet, stirring to coat the chicken and green beans in the sauce. Allow it to simmer for an additional 3-4 minutes until the sauce thickens slightly.
Step 7: Assemble the Bowls. In meal prep containers, add a generous scoop of rice, followed by the chicken and green bean mixture. Top with chopped scallions for an extra burst of flavor.
