refried beans in the bottom of a (1-quart) shallow edged serving
dish (you can use a transparent dish if you'd like). Sprinkle the
seasoning packet over the beans. Layer the diced tomatoes over the
beans, the sour cream over the tomatoes, and the guacamole over
the sour cream. Sprinkle the entire layered dip with cheddar
cheese, followed by green onion and finishing it off with a layer
of black olives. Cover and refrigerate until ready to serve.
