Pre heat oven to 180 degrees C

put the melted butter in microwave for about 30 seconds full power. Add flour and whisk.

Add 1/4 cup of the milk and mix to a paste, then add another 1/4 cup and whisk. Then add the rest of the milk.

Microwave for 2 mins.

Remove and whisk again.

Back in microwave for 1 more min.

Repeat until kinda thick, bit thicker than tomatoe sauce.

Add a cup of grated cheese, whisk.

Add some parsely.Whisk, I like whisking

Drain the tuna and add to white sauce.

Set aside.

Cut crusts off bread.

Butter one side, put in muff tin butter side down.

Press the bread in so they conform to the sides

I use a 12 bucket tin but mix makes about 18

Spoon white sauce/tuna mix into bread cases.

Put in middle of oven for about 20 mins or untill top edges of bread are nicely brown, not black aey?

Take out of oven and remove from muff tin. Cool on a wire rack, cause they bloody hot and might fall apart a bit.
