a mayonnaise substitute?

[mrbigstuff]

OK, I'll 'fess up somewhat: this thread was meant to find out a few things about you all.

And, I still hate light mayo! and I can't imagine mixing yogurt in with my tuna, which is the only place I use mayo.

I often make tzatziki and eat a *lot* of it usually with meat. Truth be told, I've never tried it with tuna but I suppose I can sacrifice a can o' tuna to check it out.

Thanks, all, for the suggestions. I will try check out a couple of the things you folks mentioned. Baconnaise sounds great... the vegenaise, well, not so much, but I will give that a taste, too.
