I'm finally down to the last 3 sweet pots out of the 2kg I ordered by mistake!! I thought I'd make soup out of them. Any ideas on what else I could put in? I don't have any carrots left. I've got frozen onion and some garlic and a few jars of dried herbs. I have a ton of fruit, apples especially. Could I put a few in or just keep them for a crumble?
