This is a recipe that I've had for years and once again have no idea where it came from. My family likes it better than any we've ever had in a restaurant. This is also great the second (or third) day. The amount of onions you use will depend on how strong you want the onion taste to be. In my opinion, you can have too much onion, so I usually tend to stay closer to the 3 cups rather than 5.
