1. Mash the avocado and cucumber together until only small lumps remain.
2. Stir in remaining ingredients.
3. If not serving immediately, cover with plastic wrap pressed onto the surface and refrigerate. Avocados tend to turn brown when exposed to air but it won't affect the taste. If the surface of the dip has turned brown while it tis chilling, just stir well before serving.
4. Serve with tortilla or other chips. Nacho Cheese Doritos are very good with this dip.
