We eat out a lot and tonight are going to a bbq at a friends. I don’t know what will be served, most likely home kill sausages and steak and salads, potatoes. We have been asked to bring a salad. But I don’t know what to do for myself. I can’t exactly take scales and weigh all my food hahaha. I was thinking of precooking some prawns and taking something else for myself all weighed out but wouldn’t that seem rude? What do others do when they are invited out?
