1Prep Teriyaki Sauce: In a small bowl, whisk together soy sauce, mirin, cooking sake, brown sugar, grated ginger, and minced garlic. In a separate tiny bowl, mix cornstarch with 1 tablespoon water to create a slurry.
2Cook Teriyaki Chicken: Pat chicken thighs dry. Heat a medium skillet over medium-high heat. Add chicken and cook until browned on both sides and cooked through, about 5-7 minutes. Pour the prepared teriyaki sauce over the chicken, bring to a simmer. Stir in the cornstarch slurry and cook, stirring constantly, until the sauce thickens and coats the chicken, about 1-2 minutes. Remove chicken and slice into bite-sized pieces.
3Prep Veggies & Rice: Cook sushi rice according to package directions if not already done. Thinly slice the cucumber and avocado. Cook shelled edamame if frozen. Shred carrots if not pre-shredded. Chop green onions.
4Make Spicy Mayo: In a small bowl, whisk together mayonnaise and sriracha until well combined.
5Assemble Your Bowl: Place cooked sushi rice as the base in a bowl. Arrange sliced teriyaki chicken, cucumber, avocado, edamame, and shredded carrots artfully on top of the rice.
6Finish & Serve: Drizzle the spicy mayo over the bowl. Garnish with chopped green onions and sesame seeds. Serve immediately.
