Looking for a healthy steak? Here it is: a scrumptious sirloin, flash-cooked so it retains all its fabulous flavours and surrounded by plenty of fresh vegetables. Sirloin is among the leanest cuts of steak, yet is wonderfully succulent.
*For a tasty change, roast the potatoes instead of boiling them.
*Use 450g (1lb) cubed sweet potatoes in place of the new potatoes.
*Replace the green beans with mangetout or sugarsnap peas.
*For a mellow flavour, toss the red onion in balsamic vinegar instead of white wine vinegar.
*A 125g (4½oz) serving of beef (which is what you get in this recipe) provides a whopping supply of vitamin B12. It is also an excellent source of iron and zinc.
*The red onion in this dish is particularly healthy for your cardiovascular system. In addition to being high in fibre, it offers large amounts of antioxidants, particularly quercetin, a potent flavonoid linked to a reduced risk of cancer, cardiovascular disease and cataracts.
