Prepare your station: Preheat the oven to 400°F (200°C).
Line a large baking sheet with parchment paper for easy cleanup.
Season the beans: In a medium bowl, toss the trimmed green beans with avocado oil until they are lightly and evenly coated.
Assemble the bundles: Working with one half-slice of bacon at a time, tightly wrap a small bundle of 4-5 green beans.
Place the bundle seam-side down on your prepared baking sheet to prevent it from unraveling.
Repeat with the remaining beans and bacon.
Season and bake: Arrange the bundles in a single layer, leaving a little space between each.
Sprinkle them evenly with salt and pepper.
Bake for 25 minutes, or until the bacon is perfectly crisp and the green beans are tender-crisp.
