Balsamic Green Beans - cooking recipe

Ingredients

1 lb green beans (I use frozen petite green beans)
1/4 cup balsamic vinegar (or to taste)
1/4 cup parmesan cheese, shredded
1 tablespoon butter

Preparation

Place green beans in microwave safe dish with the butter. Cover and cook on high for five minutes.
Add vinegar and parmesan cheese. Cook on high five more minutes (covered).
Stir to make sure the beans are well coated with the vinegar mixture.
Serve and enjoy!
These would work well with fresh green beans too. You would just need to adjust the cooking time.
Ingredient amounts can be adjusted to suit your taste. I will sometimes increase the parmesan cheese and use 2 tablespoons of butter.
