This isn't crock pot but it's really very good. I'm sorry I just make this my measurements will not be good.
2 8 oz pkgs cream cheese, softened
1 cup med taco sauce (or mild, what you prefer, this is where I don't measure)
chopped black olives
shredded cheddar cheese (co-jack, pepper jack, whatever)
whatever else you put on your tacos
blend cream cheese and taco sauce well with electric mixer. Spread in serving platter about 1/2 inch thick???
Top with lettuce 1st, then the rest as desired.
Serve with tortilla chips and scoop away!!!!
