I just don't care for the taste or consistency of low cal/low fat/canola/fat free or whatever mayos. To satisfy mayo cravings, I have two suggestions:
- cut regular mayo 50/50 with fat free yogurt - immediate 50% savings and a snappier but perfectly "mayo-like" taste
- try fat free Miracle Whip. Since it doesn't taste like mayonnaise anyway, thre change in taste doesn't bother me.
