Stir together the beans, TOSTITOS® salsa, cheddar cheese and 1/4 cup of the sour cream.

Spread evenly in the bottom of a rectangle sheet pan (about 9" x 12").

Mash together the avocado, lime juice and salt. Spread evenly over the top of the bean mixture in the pan.

Put the rest of the sour cream in a piping bag with decorator tip and pipe field lines and a 50 yard marker on top of the guacamole layer (see picture).

Allow to chill in the refrigerator until ready to serve with the TOSTITOS® Scoops!
