yeah, but cheese made from goat's milk comes in just as many styles as cheese made from cow's milk...and i think we'll all agree that there is WORLDS of difference between limburger and cheddar! if we're talking about the soft, crumbly, spreadable stuff, then yeah, i'll say goat cheese is more strongly flavored than feta. but then again, i buy greek feta, made of sheep's milk the way it should be, so i'm biased.
but the original question: heck, yes, toss some feta crumbles on there! i'm a big fan of using those similar ingredients and stuffing boneless skinless chicken breasts with them, then either pan-searing or tossing on the grill.
