Cheesy Hot Dog Bake with Chili and Onion Mustard

Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking dish.

Tear up the hot dog buns and place them at the bottom of the dish. Cut the hot dogs into bite-sized pieces and layer them over the buns.

Pour the chili over the hot dogs, then sprinkle the chopped onion on top. Spread the mustard over the onion layer before adding the shredded cheese.

Bake in the preheated oven for 30 minutes until the cheese is melted and bubbly.
