Melt the unsalted butter in a large skillet over medium heat, taking care not to burn it. Add the ground beef and begin to cook, breaking it apart with a spatula. You'll want the meat to be browned but not overly crispy, allowing each piece to soak up the flavors that follow

With the beef beautifully browned, it's time to incorporate your prepped veggies — the onion and bell pepper. Mix them into the ground beef, letting them sweat and release their sweetness. The fragrant garlic joins the party next, stirring frequently to prevent any chance of it burning and becoming bitter.

Pour in the sugar-free ketchup, your tangy Worcestershire sauce, and the apple cider vinegar. Next, infuse the mixture with the complex notes of smoked paprika, cumin, chili powder, and an optional pinch of cayenne for those who favor a kick of heat.

Season the meaty mixture with salt and freshly ground black pepper, adjusting it to suit your personal preference. Let your Sloppy Joe blend simmer for about 10 minutes, allowing the sauce to thicken and the taste to deepen. This simmer is vital, as it marries all the components into a mouth-watering filling generous enough to lavish upon your favorite keto-friendly buns or lettuce wraps
