Slice each avocado in half and carefully remove the pit. Using a spoon, scoop the flesh into a mixing bowl. Mash the avocado with a potato masher or fork until you achieve your desired consistency, whether chunky or creamy.

Add the finely chopped red onion, seeded jalapeno, diced Roma tomatoes, chopped cilantro, and salt to the mashed avocado.

Squeeze fresh lime juice over the mixture to add brightness and prevent browning. Mix all ingredients thoroughly to combine flavors evenly.

Serve the guacamole fresh with tortilla chips, tacos, or as a topping.
