In a bowl fork smash the avocado with the roasted garlic until you have reached the desired consistency. Add in the onion, lemon juice, parsley or cilantro, hot pepper (if using), tomato and salt. Mix well and taste. Cover tightly and refrigerate, you may need to stir before eating as the avocados can oxidize on the air exposed areas (turns grey in color).
Note: **Always add the tomato last as if you decide to mash the mixture some more you won't mash the tomatoes into pulp and juice.
