Changing the recipe slightly - have you thought of making a fish lasagna? Here's a recipe a friend gave me:
1 tablespoon oil, half a red pepper and half a green pepper finely
chopped. 8oz prawns, 1 large can pink salmon, grated rind and juice
of half a lemon
half a teaspoon dried tarragon (optional), 2 tablespoons chopped fresh
parsley, salt and pepper.
sauce - 2 oz margarine or butter, 3 oz plain flour, 2 pints milk
also 2 oz grated Cheshire or other cheese, sheets of lasagne
Lightly fry pepper in oil till slightly softened, stir in prawns,
salmon, lemon juice and rind, tarragon and parsley and seasoning.
Make white sauce, stir until thickened, stir fish mixture into sauce.
Layer sheets of lasagne and sauce mix finishing with sauce on top,
add grated cheese.
Bake 35 minutes 160C fan oven. Cover for the first 25 minutes and
remove for last 10 minutes of cooking time.
My notes:-
I have made this using a pack of fresh "fish pie mix" about 300 grams
from Tesco which I quickly microwave for a couple of minutes with some
lemon juice and then add a pack of fresh prawns. My main problem is I
use a large stoneware dish which takes a lot longer to cook through so
I allow 1 hour at 180C fan oven.
It tastes good and I have frozen any leftover portions to microwave at a later date.
