Halve the avocados, remove the pits, and scoop the flesh into a large mixing bowl.

Add the lime juice and salt, then mash with a fork or potato masher until you reach your desired consistency.

Fold in the diced red onion, chopped cilantro, and chipotle chili powder until evenly combined.

Taste and adjust seasoning if necessary. Serve immediately with tortilla chips or as a topping for nachos.
