I like to make it with mayo & sour cream (mixed 1/2 & 1/2)... and I don't use too much... just enough to coat everything...
finely chopped onion & red/yellow/green peppers... chopped scallions are good too...
and chopped fresh dill...
S&P to taste...
and chopped hard boiled eggs...
I don't like celery in any salad that uses mayo...
it gets way too watery if it sits long enough to meld all the flavors of the other ingredients...
I just hate a watery or too mayo'y salad!

a little chopped crispy bacon is a good addition also!

For presentation, I sprinkle some sweet Hungarian Paprika on top too...

sorry, I don't have amounts for each ingredient, I use the "that looks like enough" method!
