1. Prepare the chicken: Start by patting the boneless, skinless chicken breasts dry with paper towels. This helps them brown better. Then, cut the chicken breasts into 1-inch bite-sized pieces. Aim for uniform pieces so they cook evenly.

2. Season the chicken: In a medium bowl, toss the chicken pieces with the salt and black pepper. Make sure each piece is lightly coated.

3. Melt the butter: In a large skillet or frying pan, melt the unsalted butter over medium heat. Swirl the pan to ensure the bottom is evenly coated.

4. Cook the chicken: Add the seasoned chicken pieces to the hot skillet in a single layer. Avoid overcrowding the pan, as this can steam the chicken instead of browning it. You might need to cook the chicken in two batches. Cook for 3-4 minutes per side, or until the chicken is golden brown and cooked through. The internal temperature should reach 165 F (74 C).

5. Make the honey butter sauce: Once the chicken is cooked, reduce the heat to low. Add the honey, apple cider vinegar, garlic powder, and onion powder to the skillet with the chicken. Stir gently to combine everything.

6. Glaze the chicken: Continue to cook for another 2-3 minutes, stirring occasionally, until the sauce thickens slightly and coats all the chicken pieces beautifully. The sauce should cling to the chicken, creating a lovely glaze.

7. Serve immediately: Remove the skillet from the heat. If desired, sprinkle with fresh chopped parsley for a pop of color and freshness. Serve the honey butter chicken bites hot.
