really quick potato omlette

This was an afternoon school snack for Finn.
Really quick and easy if you have left over roast potatoes.
I used a small 6 inch based cast iron pan.

Start  by putting the pan on medium heat,  then turn on the grill.
Chop up as many potatoes as you want.  I think I used about 3 along with some roasted onions and garlic that were also leftovers.  Use what ever cook vegetables you have.
Add some butter and oil to the pan and gently saute the potatoes, add some salt and pepper.
Beat together 3 eggs and add to the pan.
Let it sit until the edges start to firm up.  At that stage I added a handful of tasty cheese and a little bit of chopped up ham and then bung it under the grill to brown up.
It easily comes out of the pan.
