Cut the avocados in half, remove the pit, and scoop the flesh into a mixing bowl.

Add the diced tomato, chopped red onion, minced jalapeño, lime juice, and salt to the bowl.

Using a fork, mash the avocado and mix all the ingredients together until well combined but still chunky.

Taste and adjust seasoning with more salt or lime juice if needed.

Transfer the guacamole to a serving bowl and garnish with chopped cilantro if desired.

Serve immediately with tortilla chips or as a topping for tacos.
