Minted Green Beans with Red Onion

1. 1

   In a kettle of boiling water cook the beans for 2 to 4 minutes, or until they are crisp-tender, transfer them with a slotted spoon to a bowl of ice and cold water to stop the cooking, and drain them well.

2. 2

   Pat the beans dry with paper towels and chill them, covered, for at least 3 hours or overnight.

3. 3

   In a large bowl whisk together the mustard, the vinegar, and salt and pepper to taste, add the oil in a stream, whisking, and whisk the dressing until it is emulsified.

4. 4

   Add the beans, the mint, and the onion and toss the mixture until it is combined well.
