Step 1

Cook beans in boiling water until crisp-tender (about 2-3 minutes).

Step 2

Drain beans, rinse with cold water, and transfer to a bowl full of ice water. Once cool, drain the beans again and set aside.

Step 3

Meanwhile, in a large bowl (or in a jar with a lid) whisk or shake together garlic, herbs, olive oil, and vinegar until completely combined. Season with salt, to taste.

Step 4

Once beans are cool, add them to the bowl along with the onion and tomatoes. Toss everything together until coated in dressing. Cover and refrigerate until ready to serve.
