In a large skillet over medium heat, add 1 tbsp oil. Add the onion and cook for 3-4 minutes.
Add the ground beef, breaking it apart using a wooden spatula, and cook for another 4-5 min.
Stir in the ketchup, tomato sauce, Worcestershire sauce, Dijon mustard, sriracha seasoning, hot chile honey, molasses, minced garlic, orange zest, and a pinch of ground cloves. Season with salt and pepper to taste.
Reduce the heat to low and simmer the mixture for 10-15 minutes, or until the sauce has thickened.
Serve the Sloppy Joe mixture on the hamburger buns, and enjoy!
