This is a good recipe if you want to make your own queso!!!
½ c chopped onions
1 T oil
1 T flour
1 c. milk
½ lb. Velveeta cubed
2 sm cans chopped green chili peppers
In skillet sauté onions in oil. Add flour and blend. Gradually add milk and heat until smooth. Add cheese and drained chili peppers. Blend until heated and thick.
If you want it thicker you can increase the flour a little or add a little less milk. This is great with Fritos or chips.
