Chicken Lasagna

I am tempted to eat lasagna few days ago, and found this recipe...

Ingredients:
250g lasagna sheets, cooked, and drained
280ml milk
1 bay leaf
1 onion
3-4 white peppercorns, lightly smashed
200g chicken fillet, minced
1/2 an onion, chopped
170g tomato puree
3/4 tsp dried basil
3/4 tsp dried oregano
2 tbsp water
Salt and pepper to taste
30g butter
25g plain flour
2 tbsp grated or shaved Parmesan cheese
1 tbsp chopped parsley

Pour milk into a small saucepan.
Add bay leaf, onion an peppercorns.
Bring to just a boil, then remove the the fire and leave aside.

Put chicken minse in a non-stic saucepan and fry briskly to brown the meat.
Add the onion.
Toss well and cook until onion turns soft.
Stir in tomato puree, basil, oregano and water.
Cover the saucepan with a lid and cook over a medium low heat for 8-10 minutes.
Add salt and pepper to taste.

Melt butter in a clean saucepan.
Stir in flour and cook until turns frothy.
Bring saucepan away from the heat and strain in the cooled flavoured milk.
Bring the saucepan back to the fire and whisk until the white sauce begins to boil and thicken.

Lightly grease a straight-sided ovenproof dish.
Line the base of the dish with one layer of lasagna sheets.
Spread on a thin layer of the white sauce.
Add a layer of the cooked minced meat.
Repeat the layering until all the lasagna sheets and cooked mince are used up, finishing with a layer of lasagna sheets.
Sprinkle with Parmesan cheese and parsley.

Bake at 190°C for 13-15 minutes.
