This is really easy to make but looks fancy. Serve as an appetizer if you have friends over for dinner, or just enjoy on your own. Unless you have a really big avocado, there will probably be leftover salad, which you can enjoy on the side. Have the other half of the apple as a snack.
TECHNIQUE TIP: To pit an avocado, first cut it in half lengthwise around the perimeter of the pit, then twist the halves apart. Whack the blade (not the tip) of the knife into the pit so it sticks. Gently twist the knife to remove the pit. Knock the pit on the edge of the sink to dislodge it from the knife.
