Grilled savory potatoes

A couple days ago it was really hot again! We were making burgers & I wanted something else but didn't want to heat my oven.  I decided to grill some potatoes on barbq.  I stumbled across this recipe for savory potatoes.  It might sound weird to have mayo in mix but these were delish!!  I added more cheese and used Italian herbs instead of fresh parsley.   I'll be making these for sure!!  Enjoy
