I'm hungry after reading all of these yummy suggestions.
I love corned beef with mash and white sauce. We never have it though as DH doesn't eat it.
Another comfort food for me is creamy mashed potato with a blob of butter of lots of black pepper. Again, DH doesn't eat mashed potato! lol
Faves in this house when we're looking for comfort food are:
Chicken, mushroom & spinash risotto (nice and cheesy!)
home made chicken parmas and veg
roast lamb and crispy roast veg with lots of gravy
lasagne
apple crumble (homemade with lots of crumble!) with cream or icecream.
