One of my favorite (and quick) seafood dishes is just frozen shrimp! I take the pre-cooked frozen small shrimp, and I pour about a cup or so into a frying pan (no oil or anything!). I heat up the shrimp, and all of the ice on the shrimp becomes water. I let it cook in its water, stirring it every so often. Just as the water evaporates, I add some soy sauce (zero points!), salt, and pepper, and pretty soon I have a nice [tasty] cup of shrimp.
1/2 cup of shrimp is 1 point. PLUS it's a filling food.
I usually eat about a cup full. It's such a nice snack or side dish.

Also, pre-cooked frozen shrimp comes in the jumbo size. I LOVE to eat this chilled. You pour some into a bowl, let cool water run over it (if it's still frozen), and stir it every once in a while so that the they become unstuck. About five minutes later, the shrimp has defrosted, and it's ready to eat!
I don't even dip it in cocktail sauce! I just love it plain! Such a healthy (filling) snack!
