So tasty! I doubled the amount of cheese in the mash and was generous with the topping. Loved by all and will definitely make it again.

Superb dish - easy - delicious - also keeps warm because of the last minute grill (mashed potatoes go lukewarm for me if I start mashing etc for ages). This is a seriously good recipe.

Brilliant mash dish, I left out the mustard and hubby doesn't like it, but sneaked the mustard into the pot roast beef ( he didnt notice it in there !!) The mash is creamy and cheesy even though there is only a small amount of cheese in it. Prepared ahead and reheated in the oven. Yum
