Mixed Vegetable Gratin
Preheat the oven to 350 F/180 C/gas mark4.
Wash and slice the leeks and carrots, divide the cauliflower and broccoli into florets, and cut the potatoes into small pieces. Steam them until just cooked but still fairly firm to the bite. Place in a large buttered casserole dish.
Melt the butter in a pan, stir in the flour and cook for 1 minute.
Pour over the vegetables and bake in the oven for about 20 minutes or until heated thoroughly. Serve immediately with a side salad and follow with a fruit dessert such as blackcurrant fool.
