Cube the velveeta, put in slow cooker with 1 cup of sour cream, and 1 cup of taco sauce. Cook on high for 1 1/2 to 2 hours, stir often. Add milk to thin. You don't want the cheese to be gloppy. I kept the cheese on high during the party, so the cheese would stay thinned out, stir often, and keep adding milk if the cheese thickens.
Guacamole directions:
Take 4 to 5 avocados, and mash with a fork and add 1/4 cup sour cream, 2 tablespoons lime juice, and a dash of salt, mix lightly.
Assemble Nacho Bar:
Put the cooked and seasoned ground beef in a small slow cooker on low, or a pan with a lid works fine. Put all your toppings in little dishes (I got mine at the dollar store, they came with lids). Put the chips in a big bowl. I got the white paper nacho trays from a restaurant supply store (Cash and Carry), but you can get them at Costco too. Invite all your friends over for the big game, I think they will be impressed!
