Start by cutting the ripe avocados in half lengthwise, remove the pits, and scoop the flesh into a medium bowl. Mash gently to desired chunkiness.

Squeeze lime juice over mashed avocados to prevent browning and enhance flavor. Mix until combined.

Slice off the kernels from the grilled corn and add to the avocado mixture. Stir gently to combine.

Finely dice the red onion and chop the cilantro. Add both to the bowl and mix evenly.

Season with sea salt, black pepper, and cumin. Stir until all ingredients are incorporated and adjust seasoning to taste.

Serve immediately with tortilla chips or veggies for best freshness.
