In a large bowl, combine the cooked halibut, bread crumbs, salt, cayenne pepper, Old Bay seasoning, scallions, red bell pepper, garlic, Worcestershire sauce, fresh parsley and dill, shallots, mayonnaise and egg. Gently fold the mixture with the cooked halibut. Shape the mixture into 6 – 3/4 inch thick patties and place on a plate. Refrigerate for 1 hour to allow the mixture to firm. In a large skillet, melt the butter and add the olive oil over medium- low heat. Add the halibut cakes and cook until golden brown, 3-5 minutes per side. Remove from the heat. Set aside on a serving plate. In a small mixing bowl combine the orange juice, balsamic vinegar, avocado oil and a touch of salt. Whisk well and gently toss the micro greens in enough dressing to lightly coat. Top the halibut cakes with the micro dressed salad and enjoy!
