I am loathed to throw out any kind of food, and Mondays I usually have lots of left-overs. Depending on what I have, a gratin or a soup is usually what I go for.
Today I had four potatoes, one carrot, a bit of cheese (it has survived since Christmas - we bought a huge edamer that just never ends), half an onion, two bits of sausage (Norrlandsfalu - a boiled and lightly smoked sausage- and a spicy one I can´t remember the name of), 200 ml of cream, and some kebab sauce.

I put all the veg and cheese through the food processor, using the coarsest grater, diced the sausage, and put it all in an oven dish. I usually put in a layer of veg mix, then sausage, then the rest of the veg. I mix cream and sauce with a bit of spice, like tabasco and Worchestershire sauce and pour it over the whole thing. I then sprinkle some bread crumbs on top, to prevent the cream from burning and going all icky. This is traditionally done to Janssons Frestelse (= Jansson´s Temptation), a potatoes au gratin dish that is seasoned with anchovy (I will certainly do it later on the blog), and I really like the texture of the surface so I imported the technique to all my gratins.
I leave it in the oven for 50 minutes at 200 degrees Celsius, and if dinner is delayed I just turn the oven off and let it sit in the remaining heat. I serve it with a fresh vegetable, we seem to like cucumbers at the moment, and a glass of saft.
This size of gratin usually feeds the two of us and one person besides. I often put any left-overs on a plate, put a soup plate on top, stick it in a plastic bag and freeze it, for the next day when I eat alone (this happens most weeks). It´s like a home-made microwave meal, very handy!
