I have been known to cook extra veg and potatoes just to be able to make this the next day. I'm sorry quantities aren't exact but it depends what you have left over. You need more or less equal veg to potatoes and you need mainly green veg such as cabbage, peas, sprouts but I also put in some leftover roasted carrots and parsnips as well.
It's hardly a recipe but my method is here ...
Bubble & Squeak
salt and pepper
low calorie spray oil
I find the easiest way to mash them is to put them in a roasting pan so you have plenty of space, Mash the veg and potatoes together well I use a potato masher but you can use a fork too just make sure everything is well mashed and mixed. Season with some salt and pepper while mashing.
Spray a small frying pan with the spray oil and place a few spoonfuls of the mixture in so when pushed down to fill the pan you have a layer about 5cm thick. Fry over a medium heat for 5-10 minutes then try and peek underneath hopefully there will be a nice brown crust developed.
Tip out onto a plate then respray the pan and slide it back into the frying pan to make a crust on the other side.
I like to serve topped with fried or poached eggs.
