Peel and chop the avocados into 1/2" pieces. Lightly mash with a fork, leaving plenty of chunks. Add the onion, green chile, cilantro, lime juice, salt, and pepper. Stir to combine and taste.
Adjust the lime, salt, and pepper as needed. Sprinkle with additional onion and cilantro, if desired. Serve immediately with tortilla strips or cover tightly and refrigerate until ready to serve. Enjoy!
