Add the chopped streaky bacon to a cold pan and slowly bring the heat to medium-high.
Cook the bacon until it turns crispy. Set the bacon aside, but keep the rendered fat in the pan.
Add butter to the pan and gently melt over medium-high heat.
Add the Brussels sprouts and season with a liberal pinch of salt.
Cover the pan and cook the sprouts for 10-12 minutes or until tender and charred well. Stir occasionally to ensure an even colouring.
Stir the bacon through the cooked sprouts and season with black pepper. Serve Hot.
