I decided to post this delicious, yet quick, dip from Penzey's Spices. I've made this for several years and everyone loves it. The recipe says, "Two important things: pick good avocados and keep the finished guacamole sealed airtight to keep its vivid green color. Layer saran wrap right on top of the guacamole, then cover the bowl and refrigerate until serving time." The last time I made this, I forgot the lemon juice and it still tasted great!
