Add chopped tomato, onion, salt, chili powder, and juice of one lime. Mix well.
Smooth the guacamole out on top and spread mayonnaise to cover the entire top surface of the guacamole.
Place guacamole in the refrigerator until ready to eat. When ready to eat, thoroughly mix the mayonnaise into the guacamole. The mayonnaise keeps the guacamole from browning before you're ready to eat it and makes the guacamole nice and creamy!
