Cut the avocado in half and scoop the middle of both avocado halves into a bowl, leaving a shell of avocado flesh about 1 / 4 - inch thick on each half.
Often when I come home from running, I slice an avocado in half, twist it and take out the pit, then dice the flesh in the shell with a sharp knife, making it easy to scoop it out of the shell with a spoon.
