In a food processor container, combine the tomatillos, cilantro, onion, chilies and garlic.
Pulse until combined but still slightly chunky.
Add one of the avocados; process just until incorporated.
Remove from processor; fold in remaining avocado cubes, keeping mixture chunky.
Serve with fresh cut-up vegetables such as jicama or carrots, on salad greens, or with tortilla chips.
