1. Clean and remove any wilted leaves from the Brussels sprouts. Trim the bottoms and slice the Brussels sprouts in half. Set aside.
2. In a cast-iron skillet, cook the bacon over medium-high heat. When crispy on both sides, remove to drain and cool on a paper towel. Crumble the bacon and set aside.
3. Leave the bacon fat in the pan and add the Brussels sprouts.
4. Allow them to cook for about 5 minutes over medium heat, stirring every now and then, so that all the edges start to get crispy. Add the brown sugar, stir it in, and cook for a minute or two more. Taste one to make sure the sprouts are cooked through.
5. Remove from the heat and add the sliced pears.
6. Crumble and add the cheese and then the bacon. Mix everything well. Serve warm or at room temperature.
