I love avocados! I grew up with a mature, abundantly-producing avocado tree in our yard and I have missed that tree for years! I eat them with nothing but a spoon and a little seasoning. Just cut it in half, remove the pit, shake on some seasoning and eat it just as-is. Delicious!
I also make avocado sandwiches that is nothing but bread with a little mayo and slices of avocado inside. Also very yummy.
I love the flavor of avocados, so I don't like to hide it with much. Even guacamole "hides" too much of the flavor sometimes. They are high in fat, but it's the 'good' kind of fat.
