First, add your chopped into a tiered steamer with the water below and cook until all veg is tender.
Meanwhile, add the oil to a large non-stick frying pan and sear the sausages on high, turning regularly for 5 minutes.
Add the onions, rosemary and seasoning and reduce the heat slightly and stir and fry for another 5.
Add the chutney or jam and mushrooms and stir and cook for a further 3 minutes. Or until the onions look caramelised. Now's a good time to cook low and slow if desired until the colcannon veg water has flavour.
Add the wine and mustard and cook on a rolling simmer until it has reduced down to a 3rd.
Add the veg stock, or any stock you're using and the Xantham gum and stir and simmer until you get your desired consistency and remove from the heat.
Drain the colcannon potatoes and veg, place back in the pan and mash together with the seasoning and butter and serve alongside the sausages in red wine gravy. And garnish with fresh chives and enjoy!
