Take as many potatoes as you can eat.
As many carrots as you can eat.
As much green cabbage, spinach or robust, greens as you can eat -make it a butchy brassica, though.
Cook the lot, peeling the potatoes if you're up to it. I suppose you could cook them all together, if you time it right. Cook them until they are well done, then drain, mash roughly and chop up the greens further if need be. Mix, then pile the lot into a bowl and season very generously with balsamic vinegara, seal salt flakes and freshly ground black pepper. A fried or couple of poaxhed eggs on top would be good.
This should serve one. It's what I cook for me when everyone is in bed or out and I've had a shite day. Eat in bed or maybe under a blanket somewhere.
