First things first: cut your chicken breasts into small pieces. Aim for bite-sized pieces that are just the right size for your slider buns. You don’t want them too big or too small—just the perfect fit for a single bite.
Next, set up a breading station. In one bowl, combine your flour, salt, and pepper. In another bowl, beat the egg. Finally, place your panko breadcrumbs in a third bowl. Now, you’re ready to bread the chicken.
Dip each piece of chicken into the flour mixture first, making sure it’s well-coated. Then, dip it into the egg to help the breadcrumbs stick. Finally, roll it in the panko breadcrumbs, pressing gently to make sure it’s coated evenly. Repeat with all of the chicken pieces.
