Prepare salsa by combining mango, strawberries, onion, jalepeno, cliantro, and lime juice in a bowl. Toss to combine and set aside.
For the cod- salt and pepper the cod on both sides. Heat oil in non-stick saute pan on high. Sear cod on each side until fish is opaque throughout. This will take approximately 3-4 minutes per side, but use your judgment depending on the thickness of your fish.
Serve fish with generous amount of salsa spooned over the fish. Garnish with a lime wedge.
