Set your oven to preheat at 190°C fan (210°C conventional) or 374°F convection (410°F standard). Prepare two large baking trays by lining them with parchment paper.
Remove the sausage meat from its casings and place the contents into a medium mixing bowl.
Stir in the honey, both types of mustard, breadcrumbs, and the thyme leaves. Combine thoroughly to create a uniform mixture.
Slice each puff pastry sheet evenly down the center, resulting in six pieces in total.
Portion out the sausage mixture into six equal parts. Shape one portion into a log and arrange it lengthwise down the middle of a pastry strip.
Brush one edge of the pastry with the beaten egg to help seal, then fold the pastry over the meat and press gently to secure the edge.
Divide the filled pastry into six equal mini rolls and arrange them on the prepared baking trays. Repeat this process with the remaining filling and pastry pieces.
Lightly brush the tops of all rolls with the remaining egg wash to enhance their color during baking.
Bake the sausage rolls in the hot oven for about 30 minutes, or until they’re crisp, puffed, and deeply golden.
