Season tenders with salt and pepper. Place a sage leaf on each chicken tender, then wrap each with a bacon slice.
In a large skillet, heat oil over medium-high. Add tenders, sage side down, and cook until fat is rendered and bacon is browned, about 6 minutes. Flip and cook until tenders are cooked through, 6 minutes. With tongs, transfer to a wire rack set on a rimmed baking sheet to drain.
