Sweet Quick-Pickled Onions

1 large red or white onion, halved and very thinly sliced into half-moons
1 tablespoon sugar
1 tablespoon rice vinegar
1 teaspoon chile flakes
Generous amount of sea salt flakes

Combine all the ingredients in a lidded glass jar or plastic container.  Close the lid tightly, and shake vigorously for a couple of minutes until the onion slices soften, then serve.  Keep refrigerated for up to 2 days in a sealed container.
