Sometimes you just need something light and healthy that is quick to prepare. Last night was one such night. Darling daughter no 2 was invited back to her sixth form college for the annual awards evening. I am a very proud mummy as she worked really hard and got an A* and received the English award for academic achievement. It was all a bit of a rush, so before I left for work I made this easy vegetable gratin, which serves 4, and we had it with jacket potatoes, although roasties would be particularly nice.
Place your cooked veg in a baking dish. Make your cheese sauce by melting the marg then adding the flour and cooking for a few minutes on a low heat. Whisk in the milk and turn the heat up a little until it thickens, then add 3/4 of the cheese. Take off the heat and season to taste, then pour it over your veg. Sprinkle over the remaining cheese. If I was eating this immediately I would stick it under a hot grill until the cheese browns. As I reheated it I warmed it in a medium oven for 25 minutes to half an hour.
