How about that spinach dip that usually gets served in a bread bowl? It goes great with veggies for nibbles beforehand. There are also some good crab dip recipes around that you serve with crackers.
If you want something to serve as a side, how about broccoli salad?
Broccoli Cranberry Salad
4 c broccoli flowerettes, chopped small
½ onion, diced (opt)
8 oz dried cranberries
¼ c shelled sunflower seeds
8 slices bacon
1 c mayonnaise
¼ c sugar
¼ c vinegar
In a large bowl, combine broccoli, cranberries, sunflower seeds and celery. Combine mayo, sugar & vinegar to make a dressing. Pour dressing over and toss. Keep refrigerated.
Have you thought about using a crockpot? If you really want to take a hot dish, making it in the crock could be the solution. I've made Crab Rangoon (like wontons) & just kept them warm in the crock. They're not as crisp, obviously, but we were happy with them that way.
You may not want another starch, but how about a cold wild rice salad? It's unusual, but very tasty.
Wild Rice and Apricot Salad
6 oz wild rice
4 oz dried apricots, chopped
2 oz almonds, sliced or slivered
6 oz yogurt, plain or vanilla
3 oz raisins or Craisins®
2 Tbl parsley
Make rice according to directions, using no seasonings or butter. Cool slightly & toss with remaining ingredients. Chill & serve cold.
