This is one of my absolute favorite layer dips in the entire world. My mom made it all the time when I was growing up and it just reminds me of a hot summer night growing up with friends over at my parents house.
1 1/2 cups guacamole (store bought or homemade)
1 cup sour cream
1 cup salsa
1 cup shredded cheddar cheese
Spread the guacamole on a platter. Next spread the sour cream, then the salsa and finally top with cheese. Serve right away or refrigerate until ready to serve.
