This makes a good side dish to something more substantial, or as a starter.
200ml unsweetened soya milk
1 small onion
2 bay leaves
¼ tsp nutmeg, grated
pinch of salt
pinch of pepper
2tsp vegetable oil
Put the oven on at 160C. Slice the onion finely, then add it and the soya milk, water, cloves, bay leaves, nutmeg, salt and pepper to a saucepan. Bring to the boil, then take off the heat and allow to sit for 20 minutes before straining off all the herbs and spices. Measure the remaining sauce in measuring jug and, if it’s less than 200ml, add water.
In another saucepan, put the oil and the cornflour. Stir together, then slowly add the flavoured soya milk, stirring constantly. Bring to the boil (keep stirring!) and you will see it gently thicken.
Cut the broccoli up into bits and steam or boil. Drain, and then place all the pieces in the bottom of a smallish heatproof dish. Pour the passata over, followed by the Bechamel sauce. Place in the oven for half an hour until just beginning to brown.
