2 ripe avocados
1/2 red onion, finely diced
1/2 bunch cilantro leaves, finely chopped
1 tablespoon of fresh lime or lemon juice
1/2 teaspoon Celtic sea salt
A dash of freshly ground black pepper
1/2 ripe tomato, seeds and pulp removed, chopped

Cut avocados in half and remove seed.  Using a knife, make cross-hatch cuts in each half of the avocado.  Scoop out avocado flesh with a spoon, and put in a mixing bowl. Using a fork, mash the avocado. Add the onion, cilantro, lime or lemon, salt and pepper and mix thoroughly.  Just before serving, add the chopped tomato to the guacamole and mix.  Season with additional salt to taste.
