Cucumber and Pea Salad

Fill a large bowl with ice and cold water. Bring a large pot of lightly salted water to a boil. Add peas and cook uncovered until bright green, 2 to 3 minutes. Drain in a colander and immediately immerse in ice water for several minutes to stop the cooking process. Drain.

Whisk Greek yogurt, olive oil, and lemon juice together in a bowl. Add parsley, 1/4 cup basil, salt, and pepper. Stir in baby peas and cucumbers. Garnish with remaining basil and walnuts.
