I like to roughly chop up the chicken tenders before layering them on to the chicken parm sliders because it makes the final sliders easier to slice and eat. Otherwise, you have to play a bit of tetris to get them to fit onto the Hawaiian rolls just right. It also helps even things out if the chicken tenders aren’t all the same size/thickness. But feel free to simply add the chicken tenders to the sliders whole if those things don’t bother you!
