This recipe has been in my family for as long as I can remember. We only got to have it at holidays. Now, I use it for a special go-to side dish all year long. It's made from scratch but so easy there's no reason not to.
Ingredient:
2 tablespoons butter
½ cup diced onion
1 tablespoon minced fresh flat-leaf parsley
1 cup diced fresh mushrooms
2 tablespoons all-purpose flour
1 teaspoon salt
½ teaspoon ground black pepper
½ teaspoon fresh lemon juice
1 cup sour cream
2 (14.5 ounce) cans French-style green beans, drained
