Cook the couscous: Bring a large pot of salted water* to a boil. Season generously with salt. Add the couscous and cook according to package directions until al dente. Drain the couscous and rinse under cold water to stop the cooking process. Drain again, gently shaking the colander to remove excess water. Set aside.
OPTIONAL - While the couscous is cooking and cooling, sauté the asparagus and snap peas*: Heat one tablespoon of oil in a heavy large non-stick skillet over high heat. Add the sliced asparagus and snap peas. Season with salt and pepper. Quickly sauté, tossing constantly, until tender-crisp and bright in color, about 2-3 minutes. Remove from heat and transfer to a large bowl. Set aside and allow to cool.
Make the dressing: In a measuring cup or small bowl, whisk together the remaining 6 tablespoons of the oil with the Dijon mustard, lemon juice, honey, lemon zest, ½ teaspoon salt and scant ¼ teaspoon pepper. Taste and adjust for seasoning with salt and pepper.* Set aside
Toss salad: Add the cooled couscous to the bowl of asparagus and snap peas. Toss to combine. Add in the shallots and sliced radishes. Drizzle with half of the dressing. Toss to well to combine. (If serving later, cover tightly with plastic wrap and refrigerate).
To serve: Add the ricotta, chives and mint to the salad. Taste and adjust with more dressing and season to taste with salt and pepper. Finish with parmesan, lemon zest and drizzle with any remaining dressing if desired. Enjoy!
