Preheat the oven to 200C. Melt the Dairygold in a pan before tossing the halved sprouts in. Season with salt and pepper.
Line an oven tray with tinfoil and spread the sprouts in an even layer. Sprinkle with the diced bacon. Cook for 30-35 minutes turning a few times. When ready, toss into a serving bowl and sprinkle with balsamic vinegar.
