I didn't have a recipe available when I started this and didn't write anything down - just what and how much for each step as I was making this but when it turned out so delicious and was so well received - I tried to recreate it from memory so I could recreate it another time. Hope I haven't left anything out, because it really was fabulous.
Sauté peppers, onions, celery and garlic in olive oil or butter until tender. Remove from heat and toss in bread crumbs, eggs, pepper, dill and parsley.
Add crab meat and toss lightly with fork. Place 2-3 tablespoons of stuffing in middle of each fillet. Top with pat of butter and lemon juice.
Lap ends of fillet across stuffing and pin with toothpick. Place toothpick side down in generously buttered or oiled (olive oil) baking dish, drizzle on more butter or oil and lemon juice; bake 25-30 minutes at 325º F.
Place on serving dish, pour on any pan drippings; sprinkle with paprika and garnish with dill and lemon slices.
