Peel ½ orange and ½ grapefruit, then slice into bite sized servings. Quarter the other half of the orange and set it aside.
Add sliced orange, grapefruit, and onion, and toss with lettuce.
Add the remaining fruit. You can toss again, or leave on top of the salad.
Squeeze remaining orange, a quarter onto each salad as a dressing. If you prefer you can blend the juice from the orange with balsamic vinegar, but the citrus juice gives it a lovely flavor.
Refrigerate if you have time, though not essential. It gives the citrus flavors time to permeate the salad.
Top with walnuts or sunflower seeds before serving.
