Pork and Potato Casserole

I adjusted this and did for 2 of us but used 2/3 of the milk & soup mix. I found the mushroom a bit strong and would do it again with maybe cream of celery.

Oil or 1Cal spray
4 Pork Loins
1 small onion chopped
4 medium potatoes
1 can condensed cream of mushroom soup
1 can milk (fill tin from soup)
grated cheese to cover

Heat oven to Gas 5 Fan 160
Season pork loins with salt & pepper and fry till nice and brown on both sides (8-10 minutes)
Thinly slice potatoes and boil for 10 minutes
Remove pork from pan and add chopped onion, cook till lightly brown
Place pork loins in casserole with onion on top
Cover with drained potatoes
Mix soup and milk and pour over casserole dish till potatoes almost covered
Top with grated cheese and bake for 30-35 minutes till well done
