Slice the avocado in half removing the pit. Remove the skin and place the flesh into a small bowl. Squeeze a bit of lemon juice on the avocado to prevent browning. Mash the avocado with a fork until you have medium size chunks- not smooth.
Finely chop the eggs and add to the bowl. Add in the seasonings and onion. Mix well. Test for seasonings and add more lemon juice or salt if needed.
Serve chilled on whole wheat toast, with crackers or alone.
