Beth and Tim made this dip last night. They mixed all the ingredients up and put them in the crockpot on low, and left it overnight. That was too much cooking for the cheese, so this is the adjusted recipe - cook everything overnight and then add the cheese the next day.
Tim also stirred in some fresh jalepenos to spice it up, but this is quite spicy on its own.
Note: Unless you're going to have a big crowd, you might want to cut this recipe in half because it makes a lot. My 5-quart crockpot was filled to the top.
