Thaw fish, if frozen. Rinse fish; pat dry w/ paper towels. Finely shred lime peel. Peel, section, and chop lime; set aside.
In a small bowl combine lime peel, the ¼ tsp salt, and cayenne pepper. Sprinkle evenly over both sides of each fish steak; rub in with your fingers.
Sear fish in olive oil on medium high heat until opaque, about 4-5 minutes on each side.
Meanwhile, in a medium bowl combine chopped lime, strawberries, jalapeno pepper, cilantro and the 1/8 tsp salt. Serve with the fish.
