Halve the avocados, remove the pits, and scoop the flesh into a medium bowl; then, mash them with a fork to your desired consistency.

Squeeze the juice of one lime over the mashed avocado to prevent browning and add a zesty flavor.

Stir in the finely diced red onion, chopped cilantro, and minced jalapeño for a vibrant and spicy kick.

Season the guacamole with salt and black pepper, adding more to taste if desired.

Serve immediately with your favorite tortilla chips or store in an airtight container with plastic wrap pressed directly on the surface to keep it fresh.
