Sweet and Sour Green Beans

Cook green beans in boiling water to which salt has been added for 20 minutes or until desired tenderness is obtained. Drain.

While the beans are boiling, cook bacon until crisp and and set aside on paper towel to absorb extra grease.

Heat a skillet, add olive oil and onion. Cook onion until soft. Add vinegar and sugar, stirring to blend ingredients.

Add drained, cooked green beans and toss with the olive oil mixture to blend and heat through. Sprinkle with sea salt and black pepper.

Top with crumpled bacon and Parmesan cheese if desired.
