Hamburger Gravy over Rice or Noodles

This is a quick meal that I like to make when I haven't really planned ahead.  I always have the ingredients, and it's simple to make.  I just throw some rice in my rice cooker, make the gravy and there you go - dinner is served!  My kids like it too!  You can also serve it over pasta.

1 pound hamburger
1 medium onion, minced
salt and pepper to taste
3 tablespoons featherlight
2 cups water
3 beef boullion cubes

Brown hamburger and onions.  Season with salt and pepper.  Sprinkle flour on top of cooked meat.  Stir and cook for 1 - 2 minutes.  Pour in water and stir.  Add beef bouillon cubes.  Stir every minute or two, until thickened.  Serve over rice or noodles.
