We like roasted red onion, garlic and beetroot with sausage and mash these days (instead of baked beans!).
Use good sausages and nice creamy mashed potatoes. A couple of red onions cut into quarters, peeled garlic cloves and peeled raw beetroot (peel and cut up wearing those vinyl gloves otherwise they stain your hands). Roast in olive oil in the oven, add some thyme if you like, when cooked through make a glaze of about 2 tbs. of chicken stock and balsamic vinegar and reduce on the hob. It is an adaptation of an Anthony Worrall Thompson recipe - he roasts the beetroots then peels them, but I peel them first and it seems to work fine.
We had halloumi cooked on the bbq yesterday - yummy.
