Delicioso Queso

1 ½ lb. process American cheese, cubed (I use Kraft, do not use Velveeta)
1 4 oz. can green chilies, don’t drain
1 T fresh minced garlic
½ – ¾ cup diced onion

Melt cheese with milk and stir until blended.  Add chilies with liquid, garlic and onion.  Stir until onions are translucent.  Remove from heat and add tomatoes just before serving.
