Combine finely chopped red onions, minced jalapeños, half of the chopped cilantro, and a pinch of sea salt in a medium bowl.

Gently mash the aromatic mixture with a fork or potato masher until well combined.

Scoop the flesh of the ripe Hass avocados into the bowl and mash to your desired texture.

Stir in the remaining cilantro and freshly squeezed lime juice, mixing until everything is evenly coated.

Taste and adjust seasoning as needed before serving.
