Heres how and why this chicken salad upgrade has been loved for over 40 years.

I was so stubborn that I would refuse to eat it unless it was shoved into a butter croissant.

Some prefer a really simple,chicken-heavy takewith barely enough mayo to hold it together.

Others like the chicken chopped so finely, like a paste.

Then, some opt fora sweet and savory mixwith bell pepper, olives, and apple.

I like mine with a secret ingredient that balances an otherwise too-mayo-y chicken salad.

And the best part is that this trick will work with any chicken salad recipe with mayo.

Theres no hard and fast rule.
