Step 1

In a small skillet, melt butter over medium high heat. Add garlic and stir, cooking for 1-2 minutes. Sprinkle flour over the melted butter, and whisk to make a paste. Cook for 1-2 minutes, and then slowly whisk in the milk. Add green chiles, salt, and cumin. Allow to come to a gentle boil, whisking frequently, until slightly thickened.

Step 2

Turn heat to low. Add the cheese, and stir until smooth. Garnish and serve with chips.
