is this sit down, passed or buffet. If it is a passed or buffet i would go with crab balls. but if it is sit down do a micro meal. Little crab cakes maybe with a light salad of micro greens. For main course you dint want to go back to fish. either do a chicken, beef, or pork. You never want to keep the same type of proteins. I personally would go with pork. take a tender loin rub it with Cinnamon sear all four sides then bake. take onion, squash, peppers. dice them to a fine dice then sauté them off with some Italian seasoning, mix with cous couse. to plate make a bed of cous couse with ring mold or pyramid mold slice tender loin on bias..place off center of cous couse finish with balsamic syrup. (basically balsamic vinegar boiled down till it turns into a syrup basically 3/4 liquid gone)
