Melt butter in a medium pan over medium heat.
Add the celery and onions and cook until tender, about 3-5 minutes.
In separate pan, brown the ground beef & drain the grease.
Place in a large stock pot or slow cooker, add the onions and celery and all remaining ingredients and simmer for one hour or cook on low or warm for a few hours, like 3-4.
*see note for further instructions*
Place hot dogs in their buns, top with chili, then cheese and place under a broiler to melt.
If you’d like to prep everything in the slow cooker and have it ready for guests you can wrap the hot dogs in a napkin, microwave for 20 seconds to get rid of some of the grease, then add them into the slow cooker with the chili to simmer for an hour on low or warm.
Serve when guests arrive.
Or if you make the chili in a stock pot and don’t wish to add the dogs, just assemble the chili dogs in a baking pan or on a baking sheet, top with cheese and bake at 350 for 10 minutes or broil for 1 minute once guests arrive.
Everything will be done all at once!
