To make the mashed potato, chop the potatoes into 1/4. Boil the potatoes in a pot until you can poke a fork in the potatoes (roughly 15 minutes)

Peel the potatoes if you haven’t done so. I usually peel the potatoes after it’s boiled so it’s easier to peel. Pre heat the oven to gas mark 6.

In the same pot, melt the butter, add the milk, cheese, and potatoes then use the potato masher to mash everything together. Add 1 tsp of salt to taste if you prefer having slightly less butter then you have your mashed potato then season with as much ground black pepper as you prefer.

In a skillet, lightly cook your spinach leaves then drain the excess water using your hand and colander. Wipe the pan using a tissue so you don’t get the excess water in your pie.

In the same skillet, shallow fry your cod fish fillet until it is cooked then break it into bite sized pieces. In a separate pot make your white sauce if you haven’t done so.

Get an oven tray and spray some oil on the tray then brush it to spread it out evenly.

Add your fish mixture followed by the mashed potato on top and spread it evenly.

Grate as much cheese as you like and spread that on the mashed potato. Place the tray in the oven and let the pie cook until it is golden brown (roughly 20 minutes)
