This fresh, vibrant lentil salad and salmon dish is hearty yet light, perfect for warm weather. I tossed black beluga lentils, arugula, avocado, grapefruit, and red onion in a lemony dressing made with whole grain mustard, honey, and fresh dill that does double duty as the salmon marinade and ties everything together. After a few minutes under the broiler, the charred salmon is placed over the lentil salad and garnished with herbs and lemon slices. Ideal for lunch or dinner, you can pack it up for a picnic or easily pull it together on a busy weeknight.
