I love it when I find a recipe that is fast, delicious and healthy. Which is exactly why this shrimp dish is a winner. The creaminess of the avocado provides richness, which plays well with the tartness of the lemon and the spice of the arugula. You can use your favorite whole grain — I used Khorasan wheat (commercially known as Kamut), which has a buttery, rich, nutty flavor. This dish can be served hot or cold and is ideal for a light, summer meal.
