I don't like #mayonnaise and I only eat it well-blended in #tuna or #potato #salad (with #mustard really helps), or a light layer in a #BLT.
I just used #SourCream to make a tuna salad, and it works great!
It might help that I make a "#spicy" tuna salad, with mustard and #Worcestershire sauce, and sometimes with #RedPepper #flakes and #CelerySeed (not #CelerySalt), like today.
If I add #Tabasco, I don't usually add the red pepper flakes.
