I think grilled onions will be a summer time grilling fav at our house. I sliced the onions thick enough but the rings still separated. I don't know if it was the type of onion or what, but I'm going to try it again.
Great recipe! Made these last week and really enjoyed them. I did sub canola oil for the olive oil. I like that I didn't have to wrap these in foil. Thanks for posting!
