Kid friendly chicken nuggets?..?

I usually just cut up a chicken cutlet, toss it in egg, then breadcrumbs and bake.. The chicken that I have right now is frozen chicken tenderloins-- so I'm thawing them out over night to make for my neices and nephew tomorrow.. Is there something I can "soak" or marinate them in that will make them more tender (i've found the frozen chx to be kinda tough sometimes), and also that will make them even more appealling to the kids?
