Pat 1 pound chicken thighs dry with a clean paper. Cut into bite-size (about 1-inch) pieces.
Whisk together 2 Tablespoons cornstarch, 1 teaspoon kosher salt, and ½ teaspoon freshly ground black pepper in a medium bowl. Add the chicken pieces and toss until all of the chicken pieces are evenly coated.
Stir together ¼ cup liquid honey, 2 Tablespoons reduced-sodium soy sauce, 2 Tablespoons granulated sugar, and 1 Tablespoons apple cider vinegar in a small bowl. Set aside for now.
Heat 2 Tablespoons canola oil in a large, non-stick skillet over medium-high heat. Add the chicken pieces to the skillet. Cook, stirring often to promote even cooking, until the chicken is evenly browned on all sides, about 7-8 minutes.
Push all of the chicken to the edges of the skillet, and add the minced garlic to the center of the skillet. Cook the garlic, stirring constantly, until it is fragrant, about 30 seconds. Stir the chicken and garlic together and continue to cook for about 30 more seconds.
Stir in the honey mixture and stir to coat all of the chicken. Cook until the honey mixture reduces and thickens to a thick glaze-like texture, about 2-3 minutes. Remove the skillet from the heat. Sprinkle the chicken with sesame seeds if desired. Serve immediately with rice or another cooked grain.
