For nights when you need a sparkle of color, this dish is just that, in both appearance and taste. First, roast a side of salmon, rubbed with coriander and garlic, and topped with lime slices to infuse it with flavor. As it cooks, prepare this simple and bright avocado salad, spiked with lime juice, jalapeños and scallions, and tossed with gentle greens, to balance the richness of the salmon. Serve with lightly oiled pearled couscous or orzo, plain rice or cilantro rice, or crusty bread.
