Freshness is paramount to Jacques Pépin, which is why he seeks out locally caught fish.
Heat a large cast-iron or other heavy skillet over medium-high. Season the fish with salt and pepper; coat with the oil. Add to the skillet and cook until browned and almost opaque in the center, about 1 1/2 minutes per side. Transfer to a plate.
Wrap the tortillas in paper towels and microwave on high until warm, about 1 minute. Fill the tortillas with the fish and the lettuce, salsa, onion, cilantro and jalapeño to your liking. Serve the tacos with the Avocado, Tomato & Mozzarella Salad.
