Green Bean Potato Salad

I made this Green Bean Potato Salad last night and served it with steak.  It's pretty healthy and tastes really good.

Green Bean Potato Salad (adapted from this recipe)
1 lb. green beans
8 small red potatoes
1/4 cup olive oil
1/4 cup balsamic vinegar
Salt
Pepper

Boil potatoes.  Boil green beans.  Mix together with the last four ingredients.

Simple & delicious!
