I’d never had a hamburger with chili sauce on it until we moved to N. Carolina years ago. I can’t remember if they put cheese on it or not, but it was very good.

Chili, slaw, mustard and onions on a burger. The best I had was the Sub Shop in Boone NC.
Boone also has a place that used Velveeta for the cheese called the Midtown Restaurant. That was really good. Both places are gone now.

If you like spicy sauce on your burgers a good secret is to go to combo fish & chips/burger stands because a lot of the secret sauces at those places will be spicy. You can never go wrong at the places that have separate Order and Pick up windows. In Tulsa, the place to go is Ralph' Fish & Burger Shack:

I always feel safe in places like this since the owners are typically self made men who are fully prepared to defend their place of business:
