Prep time: 25 to 30 minutes Cooking time: 25 to 30 minutes
Yields: 4 burgers
1 tablespoon - organic extra-virgin coconut oil
1 - large red onion, thinly sliced
2 - garlic cloves, minced ½ cup - organic chicken broth
2 tablespoons - balsamic vinegar
8 large - Portobello mushroom caps
1½ tablespoons - organic, extra-virgin coconut oil
2 - garlic cloves, crushed to a puree through a garlic press or with a mortar and pestle
Freshly ground black pepper
1 pound - organic ground bison, beef, turkey, or lamb
1 tablespoon - Dijon mustard
1 to 2 teaspoons - salt
1 teaspoon - freshly ground black pepper
½ cup - almond cheese cubes, cut to a size of about ¼ inch
fresh tomato salsa
leafy greens, such as arugula, red-leaf lettuce, or butter lettuce
fried organic egg
Preheat a grill or broiler to high heat.
For the caramelized onions, heat a sauté pan over medium heat. Add the oil and, as soon as it is hot enough to swirl easily in the pan, add the onion and garlic, then stir in the chicken broth and balsamic vinegar. Cover and cook, stirring occasionally, for 15 minutes. Remove the lid and continue cooking, stirring occasionally, until all the liquid has evaporated, 5 to 10 minutes longer. Set aside.
To prepare the Portobello buns, rub the caps on both sides with coconut oil, then with the pureed garlic. Season lightly but evenly on both sides with salt and pepper. Set aside.
In a bowl, with clean hands, thoroughly combine all of the burger ingredients, including the caramelized onions. Form the mixture into 4 burger patties about the same diameter as the mushroom caps and about 1 inch thick.
Place the burgers on the grill or under the broiler and cook for 4 to 6 minutes per side, depending on how you prefer your burger to be cooked.
At the same time, cook the mushroom caps on the grill or under the broiler until heated through, tender, and nicely browned, 4 to 5 minutes per side.
Remove the burgers and mushroom caps from the grill. Place each burger patty between two mushroom caps and serve, letting each person garnish with any of the organic fixings listed. (Vegetarians can simply pile their choices of fixings between two mushroom caps.)
