Cut avocados in half lengthwise and remove the pit.
Spoon avocado flesh into a medium-size bowl.
Mash with a fork until they are a chunky mush (but not smooth like hummus).
Stir in spices, cilantro, and lime juice. Taste-test: We always seem to need more salt at this stage, and occasionally a bit more lime, depending on the size of the avos.
Add red onion and chopped tomato.
Stir and serve in a festive bowl.
