For white fish
Season, spread some mayo on top evenly, sprinkle with paprika. Broil for about 7 minutes/inch of thickness. Simple, different, and quite good.
I like grilled fish tacos a lot too. Season with Goya Adobo with Bitter Orange, pepper, a little ground cumin and coriander. Grill, finish with a squeeze of lime and some cilantro. Load into heated corn tortillas with shredded cabbage and salsa.
