Broccoli and potato bake

I made this over a month ago, in an attempt to get us eating more veg.

Ingredients
Broccoli
Couple of potatoes, peeled and sliced thinly
Half pint milk
Tbsp flour
Tbsp butter
Cheese, I used mature cheddar

Turn the oven onto 200 to heat up. You'll need a medium pan, small pan, an oven dish and handheld blender out.

Chop the broccoli into small florets then boil in the medium pan until tender. (Or steam if you prefer). Drain then add a few of the small florets to your oven dish. Set aside the remaining broccoli for blending.

Make the cheese sauce as you would any normal cheese sauce; tablespoon of butter melted in the small pan with a tablespoon of flour added, stirred to absorb all the butter and then cooked for one minute, milk then added in small quantities with vigorous stirring to avoid lumps, then adding the cheese at the end to melt.

Arrange the sliced potato in the dish with the broccoli florets. Add the reserved broccoli to the cheese sauce and blend until smooth, turning the sauce a delicious green. Pour the sauce over the potato slices and broccoli then bake in the oven for an hour, extra cheese could be added to the top for more of a treat.
