Monterey's Tex Mex Queso Dip

Source: CopyKat

1 lb. Velveeta Cheese
1 lb. Kroger Nice and Cheesy (or any other store brand "Velveeta")
1/2 medium onion, chopped fine
1 sm. can chopped green chilies
1 Tbsp. butter

In a large saucepan, combine onions and butter, and sauté over a medium heat until the onions become clear. Then add in both cheeses, you may wish to cube these so they will melt better, and add in the green chilies. Heat until all is melted, and well heated. This reheats well, you can add a little milk to this if you like.

Notes:
Note both types of cheese are really needed for the flavor.
