Pickled mini onions are a perfect little side dish for roasts, cheese boards, lunch, patés, sandwiches… The list goes on and on. They are so easy to make, and first time I made them I felt really stupid for having paid a lot of money for similar pickled onions in the stores. I started making these as a garnish for a our extravagant veal tenderloin dish, but found they are wonderful in so many other ways. Make them one or a couple of days in advance or on the same day you want to use them, either way, they’ll be yummy little extras. They’ll easily keep for at least two…
