We usually buy Hellmann's, but I thought we'd try out Ojai organic mayo this week:

Like many forms of organic food, it's so expensive that I will eat less of it... since mayo has a kajillion calories, maybe this is a win for me? I will let you know after I try it tonight!

What brand of mayo do you buy?
