Thaw the filets in warm water and strain. Wash spinach and drain (or spin it out.) Warm a nonstick skillet over medium heat. Add olive oil and fish. Lightly dust the fish with garlic powder, paprika, cayenne pepper, and black pepper. Add a few dashes of the hot sauce to both fish and pan. When the fish is cooked on one side (half way through the filet), flip it, add sliced almonds, and dust very lightly with powdered/ground spices again. Add enough apple juice to the pan (not fish) to get it simmering and reduce. When fish is cooked though (flakey with fork), add it to a bed of fresh spinach and pour sauce over fish.
