I couldn't find a "real" recipe -- you can only buy the real gravy in Canada, but here is a cheap substitute!
Fry some home style cut french fries (or buy them from Five Guys....). Put lots of cheddar cheese on top (the real recipe calls for "squeaky" cheese = cheese curds made fresh that day). Make some brown gravy according to instructions (make it a tad more watery). Pour some gravy on top then add more cheese. Let it sit for a few minutes to melt and work itself into each other. Eat and enjoy!
(Disclaimer = it won't be as good as getting it in Canada.... you can try doing a gravy from scratch and reducing it by half....might be a little tastier than McCormick's).
