Hi all! Any suggestions for a seafood appetizer that is cooked, but served cool?

Good tasting dishes from three fishes, all of which are friendly to pregnant women and 2 of which (oily or dark fish) are especially good for them.
1) British mackerel pate. serve with rye bread or crisp toast. For example, this recipe:

2) Sardines, various recipes using fresh or canned, especially from Sicily or Portugal. Some cooked then served hot, others at room temp (if either of those fit your plan).
3) Whitefish spread or salad. A Jewish deli appetizer, which can be served on breads, crackers or vegetables (endive, cucumber etc). See this Mark Siegel recipe from epicurious:
