Chop or dice all of the vegetables to bite size of choice. The avocados will provide the creamy texture, so pre-mash if they are not ripe enough to "dissolve" on their own. Add the spices, and toss thoroughly.
Serve over lettuce and add a salad dressing or garlic vinaigrette of choice. A few tortilla chips crumbled over the top create a restaurant-style entree.
