Crunchy toasted pumpkin seeds and the salty, pleasantly funky Mexican cheese known as cotija take this otherwise classic guacamole to new heights.
In a medium bowl, lightly mash avocados. Add lime juice, onion, jalapeno, cilantro, 2 teaspoons salt, and 1/4 teaspoon pepper and mix to combine. Top with pepitas and cheese. Serve immediately or refrigerate in an airtight container with plastic directly on the surface for up to 1 day.
