One of the highlights of the week is going through the weekly organic veg bag I get delivered. Rooting around in the bag you often get a pleasant surprise or bizarre shock. This week we got a big bunch of cavolo nero and put it to good use in this omelette which was spiked with a little cumin and onion. It's one of those flavour's that taste good for you, a bittersweetness that lingers. This particular omelette was a bit thrown together, but we had just got back from after work drinks and needed something immediate and with stacks of flavour and this fit the bill nicely.
