Mix 2 cups salsa (drain off excess liquid to keep mixture thick) with 2 Tbsp. fresh lime juice; spread on bottom of a large, shallow platter. Spread 1 1/2 cups guacamole over salsa, leaving a 1-inch border of salsa around edges. Spoon 1/4 cup sour cream into a small zip-top plastic bag. Snip 1 corner of bag; pipe sour cream across top of guacamole in a decorative pattern. Sprinkle with 1 cup (4 oz.) shredded Monterey Jack cheese and 1/4 cup chopped cilantro. Serve with tortilla chips.
