Ruby Salad

What to do when life deals you beets and arugula:

Here's the recipe I promised a couple of weeks ago:

Yeah, I made up the name, what else could I call it when it's made of red potatoes, red onions, ham, and beets?
Here's what I think I put in it:
2 C. diced cooked red potatoes (skin on)
2 C. diced cooked beets (peeled)
2 C. chopped arugula
1/2 small red onion, diced
1 C. diced ham
2 hard-boiled eggs

Dressing:
1/4 C. Mayonnaise
1/4 C. Sour Cream
2 Tbsp. Dijon
Salt, pepper

And then I tossed some chopped roasted walnuts on top. Fortunately, I thought it was yum because the boys thought it was yuck. So, it lasted several days.
