1 1/2 - 2 pounds White American cheese, grated
1 to 1 1/2 cup Milk 
1 to 2 cans (4.5 oz.) chopped green chiles (Old El Paso is what I 
use)
 
Warm the milk until bubbles start to form around the edge on the 
pot.  Add the cheese a little at a time and stir until melted, 
continue until all the cheese is used.  Add the green chilies and 
stir well.  Serve with Hard taco shells or tortilla chips.  Yummy!!!
