Grapefruit and Fennel Salad - serves 8

4 pink grapefruit, halved
12 cups gourmet salad greens
2 cups coarsely chopped fennel bulb
1 cup vertically sliced red onion
Sweet pink grapefruit vinaigrette

With a small, sharp knife, remove the sections from each grapefruit half (as you would for breakfast eating), leaving the membranes behind.
Place the sections into a large salad bowl. Squeeze the juice from the grapefruit halves into a small bowl; reserve 1/4 cup juice for vinaigrette.
To the grapefruit sections, add salad greens, chopped fennel, and sliced onion. Drizzle salad with the vinaigrette, and toss gently to coat. Serve immediately.
