To make Ashley's Chicken Katsu with tonkatsu sauce, you'll first need to cook the chicken. Heat a large skillet over medium-high heat. Add the drained and rinsed chicken to the skillet and cook, stirring frequently, until it is no longer pink in the center, about 5 minutes. Drain the cooked chicken and set aside. In the same skillet, heat 2 tablespoons of soy sauce and 1 tablespoon of sesame oil. When the oil is shimmering, add the chopped tofu and stir-fry, scraping up any browned bits from the bottom of the pan. Pour the sauce over the meat and toss to coat. Serve immediately.
