If you can tolerate your chicken salad being green I like to make a avocado mayo. One of these days I should write down what I put in it but it varies a lot. Sometimes I start with guacamole, which works well for a meat salad but can be spicy for some mayo uses (what is wrong with spicy?). Avocado, salt, a splash of vinegar (if I start with guac it is lime juice). Always a dash of cayenne pepper (even if you do not want spicy a small amount of cayenne helps you taste the salt with less salt. I put a dash of cayenne in everything). If I am really going for more of a mayo taste I add a hardboiled egg yolk. Not too much or it can dry it out. If I really want creamy I work the whole thing in a food processor.
The flavor is not going to be mayo...but it is yummy and creamy. But it doesnt last very long.
