Start by mashing two of the avocados together in a bowl with a fork.

Add the lime juice and stir to combine - it will seem a little runny but remember there is more avocado to come.

Next, add some ground cumin, onion powder, and garlic. At this point you could also add some chopped fresh cilantro leaves and/or diced jalapeños, if you like.

Dice the remaining two avocados, add them to the bowl, and stir to combine. Taste for seasoning, and add salt and pepper to taste. You might also like to add more cumin, or perhaps some extra lime juice.

Transfer to a serving bowl.
