For a complete chip and dip experience, serve guacamole with tortilla chips that have been tossed with lime juice and a sprinkling of salt, a signature at Chipotle Mexican Grill.
1. Using a fork, mash avocados with citrus juice in small bowl.
2. Add cilantro, chopped onion, Serrano chilies, and salt. Stir to combine. Serve with tortilla chips, if desired.
