Instructions
 

  • In a large bowl mix together the meat, bacon, and caramelized onion along with salt and freshly ground pepper, to taste. Form into four patties.
  • Heat your BBQ or grill to medium-hot, add the burgers and cook until browned on one side, flip and brown the other side. When almost cooked; place a slice of cheese on top and allow to melt.
  • Meanwhile, lightly coat the bun with olive oil. Place on the grill, cut side down, and allow to heat. The bun should remain soft, and be lightly browned.
  • Place the burger on the bun, spread 1 tablespoon of the aioli on the top half of the bun, place a mound of arugula or spinach on the burger, top with bun and serve.
  • Prepare the Sun-Dried Tomato Aioli: In a food processor, pulse the sun-dried tomatoes with the garlic until finely chopped, then puree until smooth. Add the mayonnaise, Parmesan and balsamic, pulse until blended. Taste and adjust for salt as needed.
