What you need:
1 pound white, deli-sliced American cheese
⅔ cup of milk or half-and-half
3-4 tablespoons of canned, chopped green chiles or jalepenos
1 teaspoon cumin
1 teaspoon chipotle powder (optional)
How to make it:
If using a slow cooker, turn on to the lowest setting. Dump everything in, heat and stir until thickened.
If using a double boiler, heat the milk, chopped chiles and spices, then gradually add in the American cheese, 1-2 slices at a time, stirring until fully melted and incorporated together
