Place the tomato & white wine finishing sauce pouch in a small bowl of hot tap water to thaw for 18-20 minutes.
Bring a medium sauce pot of heavily salted water to a boil.
Blanch Brussels sprouts for 2 minutes. Drain and rinse under cold water until cooled.
Slice sprouts in half lengthwise.
Add olive oil and bacon to a large cold cast-iron pan. Turn the heat to medium and sauté for about 7 to 8 minutes, continuously stirring until the bacon is browned and crisp.
Remove the bacon and set aside, reserving the fat in the pan. Once the bacon is cool slice into 1” pieces.
Bring the heat to medium-high. Place the Brussels sprouts flat in the pan. Season with salt and pepper, cook for about another 45 seconds to 1 minute until golden brown, flip, and cook the other side until lightly browned.
Add the thawed sauce to the pan. Stir continuously and bring to a boil, then reduce to medium heat. Return cooked bacon to the pan, and cook for another 45 seconds.
