Follow these step-by-step instructions carefully to ensure your chicken bites are perfectly cooked and coated in that addictive, sticky glaze. The process is straightforward and designed for a quick and rewarding cooking experience.

1. Prepare the Chicken: Begin by patting your chicken breasts dry with a paper towel. This is a crucial step to ensure the chicken sears nicely instead of steaming in the pan. Cut the chicken into uniform, bite-sized pieces, about 1-inch cubes. Uniformity is key for even cooking.
2. Coat the Chicken: In a medium-sized bowl or a large Ziploc bag, combine the all-purpose flour (or cornstarch), salt, and black pepper. Add the chicken cubes to the mixture. If using a bowl, toss with tongs until every piece is lightly and evenly coated. If using a bag, seal it and shake vigorously until the chicken is fully coated. This light coating is what will give the chicken a delightful crust.
3. Sear the Chicken: Place a large skillet or frying pan over medium-high heat and add the olive oil. Once the oil is shimmering and hot, carefully add the coated chicken pieces to the pan in a single layer. It’s very important not to overcrowd the pan; work in two batches if necessary. Crowding the pan will lower the temperature and cause the chicken to steam, preventing it from getting that beautiful golden-brown crust. Cook the chicken for 3-5 minutes per side, until it’s golden brown and cooked through. Once cooked, remove the chicken from the skillet and set it aside on a plate.
4. Sauté the Aromatics: Reduce the heat to medium. If the pan is dry, you can add a small drizzle more of oil. Add the minced garlic (and grated ginger, if using) to the skillet. Sauté for about 30-60 seconds until fragrant. Be very careful not to burn the garlic, as it will turn bitter and ruin the sauce.
5. Create the Sauce: Pour the honey, low-sodium soy sauce, and apple cider vinegar into the skillet with the garlic. Stir everything together to combine, scraping up any browned bits from the bottom of the pan—this is where a lot of the flavor is! Bring the mixture to a gentle simmer.
6. Thicken the Sauce: While the sauce is simmering, give your cornstarch slurry (the 1 teaspoon of cornstarch mixed with 2 teaspoons of water) a quick stir. Pour the slurry into the simmering sauce while whisking continuously. Continue to let the sauce simmer for another 1-2 minutes. You will see it magically thicken into a beautiful, glossy glaze that can easily coat the back of a spoon.
7. Combine and Coat: Return the cooked chicken bites to the skillet. Gently toss the chicken in the thickened honey garlic sauce until every single piece is thoroughly coated and glistening. Let it cook together for another minute to allow the flavors to meld perfectly.
8. Garnish and Serve: Remove the skillet from the heat. Sprinkle generously with toasted sesame seeds and freshly sliced green onions. Serve immediately while hot and enjoy the incredible results of your work!
