If you want the glaze to be mild in spice, just add a pinch of pepper flakes. If you don’t want any heat, omit them completely!
If you end up running out of panko, just add another 1/2 cup or so to your dish along with some salt. 1 cup ended up being the exact amount I needed for 1.3 pounds of chicken tenders, so depending on the size of your tenders, you could be a little short.
