Green beans are one of the best kidney-diet-friendly vegetables you've got. They're delicious and you can prepare them in hundreds of ways. Here are a couple of my favorites.

Lemon Butter Green Beans
1 can no-salt-added green beans or 1 box frozen green beans
1 tablespoon unsalted butter
Juice of 1/2 lemon
Generous grinding of black pepper

Drain the liquid from the beans if you are using canned. Heat in a small saucepan, adding the butter and lemon juice. Stir or shake the pan to combine. Season with black pepper to taste.

Green Beans with Onion
1 tablespoon extra-virgin olive oil
1 tablespoon unsalted butter
1 small onion, chopped
1 cup chicken broth
1 lb. fresh green beans, trimmed
Freshly ground black pepper to taste

Melt the butter and heat the olive oil in a medium pan over medium heat. Saute the chopped onion 3 minutes, add the chicken broth and bring to a boil. Add beans, season to taste with freshly ground black pepper. Simmer 8 minutes or until tender.
