Preheat your oven to 400°F / 200°C.
Line a large baking sheet with parchment paper or a silicone mat for easy cleanup.
Arrange the bacon slices in a single layer on the prepared baking sheet.
Bake for 15-18 minutes, or until the bacon is well-browned and crispy but still pliable.
Remove the bacon from the oven and carefully transfer the slices to a separate parchment-lined surface or cutting board.
Arrange the slices side-by-side, overlapping the edges slightly to form a single bacon 'mat'.
Evenly sprinkle the shredded mozzarella over the bacon mat, then drizzle with the hot chili sauce.
Starting from one of the long ends, tightly roll the bacon mat into a log, just like you would a sushi roll.
Carefully place the bacon log back onto the baking sheet, seam-side down. Return to the oven and bake for an additional 5-8 minutes, or until the cheese is fully melted and bubbly.
Remove from the oven and let it cool for at least 5 minutes. This helps it set and makes slicing much easier.
Slice into 12 individual rolls and serve immediately.
Place bacon on a wire rack set inside the baking sheet for the initial bake. This allows fat to drip away, resulting in evenly cooked, crispier bacon.
