Never underestimate the impact of a side salad—a tasty and low-calorie addition to your meal (just don’t pour on heavy, high-calorie dressing). Garnish fish and seafood plates with small, colorful salads for added color and flavor. Buy a mesclun mix with red oak-leaf lettuce and other colors and textures; or for pungent flavor, mix arugula, mustard greens, radish sprouts and radicchio. Dress the salads lightly with a vinaigrette before plating.
