Stuffed aubergine and sweetcorn

Feel guilty about food miles now - we have onions growing on the plot but as we had already started cooking and I just nipped to the local Tesco metro to buy some only discovering they were from New Zealand afterwards. What's happening to the world if a UK supermarket has to source onions from New Zealand in July?
