Roy had a "family favorites" potluck at work...  here is one of ours

Corn and Bean Salad

This has been popular with the whole family. It’s easy to throw together, and easily multiplied.  It also keeps well in the fridge.

Serves 4

1 can black beans, drained and rinsed
1 ½ cups frozen corn, thawed under running water
1 small red bell pepper, chopped
3 green onions, chopped
½ jalapeño pepper, finely minced (optional)
¼ cup cilantro, minced

Juice from 1 large lime
¼ cup olive oil
½ teaspoon cumin
½ - 1 teaspoon mild chili powder
Salt and Pepper to taste

Put beans and vegetables in a bowl. Mix dressing ingredients in a small jar and mix with salad.  Note: there might be a bit much dressing, don’t use it all if you don’t want.
