HAMBURGER GRAVEY ON TOAST

One day my son came home from visiting and wanted me to fix this new dish they had had. I thought what kind of stuff is this. So i got to mixing this and that until I got it like he liked. He still loves this stuff.

1 Lb. Ground Chuck
4Tablespoons Marg.
1 Medium Onion, diced
1/3 Cup flour
2 to 3 Cups Milk
Salt and Pepper and (Garlic) if you like
Toast, Biscuits, Pasta or Rice

Melt the butter add the onion and ground chuck. Let fry until done. Drain off the grease and then add the flour. This makes a rue. Keep stirring until you don't see any flour. Then add the milk a little at a time until it is as thick as you like. Serve this over toast or a biscuit, over rice or pasta. You can leave the onion and garlic out and it is still good.
