Macaroni Salad GF DF

My husband grew up in the land of processed picnic foods drenched in mayonnaise and I grew up rather ignorant of them, so it is a constant struggle in our house for me to recreate these foods in a way that big Fred can tolerate.

This is my "healthy" version of macaroni salad. I made it with whole wheat pasta, but I'm sure it would be delish with white or even brown rice pasta for a gluten-free option.
I think the next time I make it, I will add chopped hard-boiled eggs.
