I first had this at a root beer stand. They top hot dogs with it, yum. Next, I found it at a Hot and Now fast food drive-thru on a burger. Again, yum. This can be really salty if using a 1:1 ratio of mayo to olives, so I gave a range. You can add more mayo (or use less olives) to suit your taste. This will make just under 1/2 c of olive mayonnaise. Use to top hot dogs or burgers, or use as a chip dip. It's delicious. Note: To make it clear, you need to work with your ratio of mayo to olives. If it seems too salty, add more mayo. If it is too bland, add more olives. I cannot speak for how olive oil mayonnaise would affect the taste or saltiness, but adjusting the amounts should have reduced the saltiness. It IS salty, and that's what makes it good. It just doesn't have to be too salty.
