Trim the green beans: Snap off the stems with your fingers or a paring knife. Rinse the beans in a large bowl of cold water, then set aside to drain.
Microwave the beans: Place the green beans in a large microwave-safe dish and sprinkle with a little water. Loosely cover the dish and microwave on high for about 1 ½ minutes. The beans should stay crisp and slightly undercooked.
Cold water shock: Immediately plunge the beans into ice water to stop the cooking and set their vibrant color. Drain and pat dry with a cloth or paper towel.
Season the beans: Lightly toss the beans with olive oil and coarse salt. Set them aside ready to use.
Lightly crisp the bacon: In a large frying pan over medium heat, cook the bacon in batches for 4-5 minutes, until just beginning to brown along the edges but still pliable. If the pan seems dry, drizzle a little oil to prevent sticking. Transfer the bacon to a paper towel-lined plate to cool slightly.
Slice the bacon: Once cool enough to handle, slice the turkey bacon strips in half lengthwise.
Preheat the oven: Set the oven to 350°F (175°C). Line a baking sheet with parchment paper.
Wrap the green bean bundles: Take about 4-5 green beans and place them at one end of a bacon strip. Roll up the beans to form a bundle and place it seam-side down on the prepared baking sheet. Repeat with the remaining bacon and green beans, leaving space between each bundle.
Season: Sprinkle with coarse sea salt and ground black pepper, then drizzle with olive oil.
Bake: Place in the oven and bake for 8-10 minutes, or until the bacon is browned and crispy.
Serve: Let the bundles rest for a few minutes, then drizzle with aged balsamic vinegar. Serve with lemon wedges on the side so your guests can squeeze lemon juice over their bundles, if desired.

Notes
Green bean preparation: Microwaving the green beans is quick and easy. This step keeps them crisp since they’ll bake in the oven as well.
Green bean texture: I love green beans that stay bright and crisp. Overcooked beans tend to become mushy, so be sure to keep an eye on them!
Turkey bacon: It's less greasy and makes it easier to wrap the green beans. Lightly crisping the bacon on the stovetop adds flavor and color, but keeps it pliable for easier wrapping.
Substitute: Can also use regular pork bacon. I prefer smoked bacon.
Seam side down: Placing the bundles seam-side down on the baking sheet helps keep them together without needing toothpicks.
Toothpicks: If your bundles don’t stay together, you can secure them with toothpicks for baking.
Make-ahead tip: Follow steps 1-3, then store the prepared green beans in an airtight container with paper towels in the fridge for up to 1-2 days.
Storage and Reheat: Store in an airtight container in the refrigerator for 3 days. Reheat under the broiler for a minute or two.
