Directions

1. Warm a large skillet over medium heat and melt the butter. Add the sliced and cook, stirring occasionally, until starting to soften, about 5 minutes.
2. Sprinkle in the brown sugar and a couple pinches each of salt and pepper. Reduce heat to medium-low, cover, and cook, stirring occasionally, until deeply golden, about 15 minutes.
3. Pour in half of the beer, increase heat to medium, and cook until nearly evaporated. Stir in the Dijon mustard and set the onions aside.
4. Preheat the grill to medium-high. In a large bowl, gently combine the bison, remaining beer, minced garlic, tomato paste, Worcestershire sauce, paprika, and a pinch each of salt and pepper. Form into equal patties, handling the meat as little as possible.
5. Grill the patties until cooked through to your liking, about 5 minutes per side, adjusting as needed based on thickness. Lightly toast the buns on the grill during the last minute.
6. Place patties on toasted buns and top with barbecue sauce, the beer-caramelized onions, roasted red peppers, and spinach. Serve immediately.
