Potato Salad

In keeping with my Summer Salad Fest, I'm posting this week's salad recipe in honor of the Southern Veggie Plate, which can comprise any combination of three or four veggies, hot or cold. One of my favorite places to eat out has wonderful veggies. When creating/serving a veggie plate at home, I use color as my guide and consult a nutrition book to make sure I've selected choices which will make a complete protein. So, with this potato salad recipe, I will serve green beans, sliced tomatoes or sliced cantaloupe, and cornbread or biscuits. Pickled beets would work well, too.

Potatoes, one per person, plus one for the pot, peeled and diced, cooked in pressure cooker, drained, and refrigerated until chilled
Onion, white, very small amount finely grated
Pickle, dill, diced
Mayo, Duke's (no sugar)
Mustard, prepared - whichever one your family likes, but I get rave reviews when I used one with a smoke flavor

What's your favorite veggie plate combo?
