last night we grilled halibut for fish tacos; guacamole, shredded cabbage & carrot, fresh salsa (tomato, hot yellow pepper, red onion, cucumber, lime, salt, cumin, cilantro) in corn tortillas
I've also done sauteed shrimp: peanut sauce, quick-pickled red onion (i.e. red onion sliced then marinated in lemon or lime juice at room temp for a few hours), cabbage, corn tortilla
