This tuna potato casserole is the ultimate meal when you are pressed for time.
Peel potatoes and slice them into thin rounds.
Cover potatoes with boiling water and bring to the boil.
Simmer for about 12 minutes - until the potatoes start to be easy to poke.
Strain the potatoes and put them in a large mixing bowl and season with butter, milk, pepper, paprika and salt.
Open and drain tuna and mix it into potatoes.
Transfer everything to a baking dish.
Bake for 20 minutes or until cheese is browned to your liking.
If you like really crunchy cheese, then for the last 5-8 minutes turn the heat up to 500F and just watch it does not burn.
Let rest on counter for 8 minutes before serving.
