Add the ground beef to a large skillet over medium-high heat, breaking it up as it begins to cook. Add in the onion and garlic, and continue cooking until the meat is cooked through and the onion is translucent, about 5 to 7 minutes. Drain any excess grease.
1 pound ground beef, 1 small yellow onion, 1 garlic clove
Add in the seasonings, stirring to combine it with the meat. Then add in the diced tomatoes, tomato sauce, Worcestershire sauce, and liquid smoke. Bring to a simmer and cook for 15 minutes.
1 tablespoon chili powder, 1/2 tablespoon cumin, 1/2 teaspoon kosher salt, 1/8 teaspoon cayenne pepper, 1/8 teaspoon black pepper, 15 ounces petite diced tomatoes, 8 ounces tomato sauce, 1/2 tablespoon Worcestershire sauce, 1/2 tablespoon liquid smoke
Preheat your oven to 350 degrees Fahrenheit. Line a rimmed baking sheet with parchment paper. Set aside.
While the chili is simmering, prepare the hot dog buns. Mix together the mayonnaise and mustard. Spread some over each side of the hot dog buns. (See note.)
8 hot dog buns, 1/4 cup mayonnaise, 1/4 cup mustard
Add the hot dogs to the prepared buns. Top with the chili (you may not use all of it). Finally, add the cheese.
