For a really superb pork sandwich, spread a crusty baguette with spiced apple and onion sauce and pack it with lean roast pork and fresh watercress.
*To prepare the apple sauce ahead, cook to the end of step 3, then cover and chill in the fridge for up to 3 days, or freeze and use within 2 months. The sauce is also good made with pears and freshly squeezed orange instead of apple juice and served in a poppy seed baguette. *For the ultimate impromptu meal, use a good bottled apple sauce or compote. *Strong-flavoured cheeses go well with apple sauce. Layer 125g thickly sliced mature Cheddar cheese with ½ thinly sliced, small red onion, 1 thinly sliced ripe tomato and 100g thinly sliced cucumber.
