G.W.
I have bought those before too and often they would have a recipe on the back. When I've done it in the past, it was basically putting the cheese in a bowl, adding milk and microwaving it one minute at a time (stirring after each minute)until it was as thin as you prefer. It usually takes several minutes. Of course, start with just a few tablespoons of milk and if you need to add more you can. I LOVE white cheese dip, one of the things I miss about my ex-brother in law (who was Mexican) was a trip to his famly's restaurant in my hometown to get the best white cheese dip on the planet!
