4 burger stacks


  • 1 egg, lightly beaten

  • 2 tablespoon olive oil

  • 2 teaspoon salt-free all-purpose seasoning*

  • ¼ teaspoon sea salt

  • 1 ½ pound ground bison (buffalo) or ground beef

  • 4 large tomato slices

  • ¼ cup Spicy Paleo Mayonnaise

  • 1 recipe Caramelized Onions

  • cup thinly sliced fresh basil

Caramelized Onions

  • 1 tablespoon olive oil

  • 1 large sweet onion (such as Vidalia or Walla Walla), halved lengthwise and thinly sliced

  • ¼ teaspoon kosher salt

  • ¼ teaspoon freshly ground black pepper


  1. In a large bowl combine first four ingredients (through salt). Add ground bison; mix well. Shape into four 3/4-inch-thick patties; lightly press centers to make dimples.

  2. Grill patties, covered, over medium heat 13 to 15 minutes or until done (160°F), turning once.

  3. To serve, stack tomatoes and burgers. Top with Spicy Paleo Mayonnaise, Caramelized Onions, and basil.

Caramelized Onions

  1. In a large skillet, heat oil over medium-low heat. Add onion, salt and pepper. Cook, covered, for 13 to 15 minutes or until onions are tender, stirring occasionally. Uncover; cook and stir over medium-high heat for 3 to 5 minutes more or until golden.


Look for an all-purpose seasoning blend that does not have any added preservatives or fillers. McCormick Perfect Pinch is a good option.
