To a hot saute pan over medium high heat, add the olive oil and butter and melt. Add garlic, onion, and bay leaf, and sweat for 1 minute. Add the mushrooms, season with salt and pepper, and cook until liquid is released and mushrooms are almost dry. Stir in the thyme and oregano. Remove from the heat and allow to cool. Remove the bay leaf.
Place the turkey in a large mixer and add the cooled mushroom mixture, mix well and season with salt and pepper. Form the mixture into 8-ounce patties. Pan fry or grill the burgers until cooked through. Serve on a bun with romaine lettuce, sliced red onions and Chunky Tomato Salsa Compote.
