Ingredients

2 cups water

1 cup quinoa, rinsed

Coarse salt

1 small shallot, finely chopped

3 tablespoons champagne vinegar

1/2 teaspoon red-pepper flakes

1/4 cup plus 3 tablespoons extra-virgin olive oil

1 small English cucumber, halved lengthwise and thinly sliced crosswise (1 cup)

3/4 cup finely chopped fresh flat-leaf parsley

Preparation

Bring water, quinoa, and 1 teaspoon salt to a boil in a small saucepan. Reduce heat; cover, and simmer until tender and water has been absorbed, about 15 minutes. Transfer to a baking sheet, and let cool on a wire rack.

Combine shallot, vinegar, and red-pepper flakes in a small bowl. Gradually whisk in oil until emulsified.

Transfer quinoa to a large bowl, and stir in cucumber, parsley, and vinaigrette. Season with salt.
