In a large mixing bowl, combine ground bison, garlic salt, rosemary, and Dijon until well-integrated.
Divide into 4 parts and shape patties, with a small indentation in the middle to help it cook through more evenly.
Heat a grill pan over medium-high heat. Add ghee and melt, followed by the burger patties and cook for 5-6 minutes. Flip and cook an additional 2 minutes for medium-rare, or longer if desired.
Remove from the grill and rest 5 minutes before serving.
Serve over a bed of arugula with sliced tomato and avocado for a bunless paleo burger option, or serve however you like!
Yields 3 bison burger patties, 4-oz each.
To make Paleo sweet potato mash:
Cook sweet potatoes in oven or microwave. (I prefer to wrap my sweet potatoes in foil and bake in the oven at 425°F (220°C) for 45 minutes so they get caramelized.)
Allow to cool to the touch and peel off potato skins.
Mash with milk, cinnamon, and salt (or seasonings of choice), until as creamy or chunky as you prefer. Serve and enjoy!
