[Beans] Sprinkle a little water and microwave french beans on high for about 1 ½ minutes. Plunge them into the ice water to stop the cooking and set the color. Drain the beans and pat dry on a cloth or paper towel.
[Bacon] In a large nonstick fry pan over medium heat, cook the bacon in batches until the slices are just beginning to brown along the edges but are still very pliable, 4 to 5 minutes depending on the thickness. Transfer to a paper towel-lined plate and let cool. Cut strips in half.
Preheat an oven to 350°F. Line a baking sheet with parchment.
Place a small bunch of green beans (about 4-5) onto the strip of bacon and roll up into a bundle. Place the bundle into the baking dish, seam side down. Repeat with remaining bacon strips and green beans and leave a little space between each bundle.
Sprinkle with some salt, fresh ground black pepper, and olive oil.
Bake in the preheated oven for about 8-10 mins until the bacon is browned and crispy.
Drizzle with balsamic vinegar & Serve with lemon wedges
