This looks like it would serve an army, but the cookbook didn’t indicate how many servings it makes. I figure you could probably cut it by a factor of four and still serve 4 to 6.

4 lbs halibut
3 lbs crabmeat
1 quart sour cream
1 jar jalapeno jelly
2 lbs grated mozzarella cheese
1 box lasagna noodles
1/2 bag spinach leaves
Use a “hotel” pan: Place a layer of halibut on the bottom and cover with uncooked lasagna. Add, in layers, spinach, cheese, uncooked noodles. Mix the sour cream, crab, and jelly for the next layer. Use parboiled or soft cooked noodles for the next layer, and top with cheese. Bake at 350 F for about an hour. The internal temperature should be 120 F.
