Medallions are usually cut from the thinner end of a beef fillet, but using pork tenderloin is a much cheaper alternative.
Prep
Clean and slice the mushrooms. Peel and dice the onion. Crush/mince the garlic. Pat the tenderloin dry and cut into slices about 2½ cm (1 inch) thick.
Cook
Heat the olive oil in a heavy-bottomed frying pan or cast iron casserole dish, and sauté the pork for 2-3 minutes each side. Remove from pan and set aside on a warmed plate. Melt the butter into the pan, add the onion and the mushrooms and cook for 5 minutes then add the garlic and cook for 1 minute more. Mix in the flour and cook for a couple of minutes, then add the wine, turn up the heat and let it bubble away for two minutes. Stir in the stock, simmer for 5 minutes, then add the thyme, the mustard and the balsamic vinegar. Give it a taste and add salt and pepper as needed. Add the pork back in, cook gently for 5 minutes or until the pork is tender, then stir in the cream. Serve with creamy mashed potatoes and the green vegetables of your choice.
