01 - Preheat your oven to 425°F. Line a baking sheet with parchment paper or foil and lightly grease the surface.
02 - In a large mixing bowl, combine the olive oil, soy sauce, cornstarch, garlic powder, salt, and black pepper. Add the chicken cubes and toss thoroughly to ensure each piece is evenly coated with the marinade.
03 - Arrange the marinated chicken bites in a single layer on the prepared baking sheet. Bake for 15-18 minutes, flipping the chicken halfway through, until they are golden brown and cooked to an internal temperature of 165°F.
04 - While the chicken bakes, whisk together the Sriracha sauce, honey, soy sauce, melted butter, rice vinegar, and minced garlic in a small saucepan. Heat the mixture over low heat, stirring constantly, until the glaze slightly thickens, typically around 3 minutes.
05 - Once baked, transfer the chicken bites to a large mixing bowl. Pour the warm Sriracha glaze over them and toss gently to ensure all chicken pieces are thoroughly coated.
06 - Arrange the glazed chicken bites on a serving platter. Garnish generously with chopped fresh cilantro or green onions, and toasted sesame seeds if desired. Serve immediately with toothpicks for easy enjoyment.
