Mediterranean Couscous and Lentil Salad, J & K

Mediterranean Couscous and Lentil Salad
From Gourmet

This salad serves 6, I would consider making 1.5 for our group.

Ingredients:
1 cup lentilles du Puy* (French green lentils) or brown lentils
3 tablespoons white-wine vinegar
1 1/4 cups water
1 cup couscous
1/2 teaspoons salt
1/4 cup olive oil (preferably extra-virgin)
1 large garlic clove, minced and mashed to a paste with 1/4 teaspoon salt
1/2 cup finely chopped fresh mint leaves
1 bunch arugula, stems discarded and leaves washed well, spun dry, and chopped
1/4 pound feta, crumbled (about 1 cup)

*available at specialty foods shops and some supermarkets

Method:
 In a small saucepan simmer lentils in water to cover by 2 inches until tender but not falling apart, 15 to 20 minutes, and drain well. Transfer hot lentils to a bowl and stir in 1 tablespoon vinegar and salt and pepper to taste. Cool lentils completely, stirring occasionally.

In a saucepan bring water to a boil and add couscous and salt. Remove pan from heat and let couscous stand, covered, 5 minutes. Fluff couscous with a fork and transfer to a large bowl. Stir in 1 tablespoon oil and cool completely, stirring occasionally.

 In a small bowl whisk together garlic paste, remaining 2 tablespoons vinegar, remaining 3 tablespoons oil, and salt and pepper to taste. Stir lentils and dressing into couscous. Chill salad, covered, at least 3 hours and up to 24.

Just before serving, stir in remaining ingredients and season with salt and pepper.
