Balsamic green bean salad

I made a single serving of this for dinner to serve cold as a side with a cheeseburger.

• Fresh French green beans, cut into 1 1/2" long pieces
• Extra virgin olive oil
• Balsamic vinegar
• Dijon mustard
• Red onion
• Grape or cherry tomatoes, halved
• Salt
• Freshly ground black pepper.

Blanch the green beans for 4 minutes, then shock in cold water. Even with thin green beans they were crunchy at 4 minutes, so if you like them softer or they are thick they'll need more time.

Prepare the dressing with olive oil, Balsamic vinegar, and Dijon mustard in a bowl.

Add the onion and tomatoes. Could also add Feta cheese here.

Add the chilled green beans.
