Ingredients
Directions
Prepare
Seed the green peppers and boil them for 2-3 minutes, then cut into shreds.
Shred the dark and light leaves of the lettuce or endive separately.
Cut the tomatoes into shreds and remove the peel and skin from the grapefruit.
Arrange and serve
Arrange each ingredient separately on a serving plate, creating a circle of light and dark green around the edge.
Pour French dressing over the arranged salad.
