Walnut and onion breads encasing an exotic turmeric-spiked filling are utterly delicious. Serve with sweetened or plain black tea any time of the day. They are perfect as a quick snack, too. Store the breads wrapped in kitchen towels, placed inside a lidded pot. They will stay there for as long as a week. Alternatively, freeze them in ziplock bags for later. To serve, bring the breads room temperature, then warm up in the oven.
