Preheat your oven to 400°F (200°C) and prepare a baking tray lined with parchment paper.

In a skillet over medium heat, warm olive oil. Sauté diced onion and minced garlic for 3-4 minutes until soft. Mix in sausage meat, sage, thyme, salt, and pepper.

On a floured surface, roll out the thawed puff pastry until thin and uniform.

Cut the rolled pastry into rectangles, spoon the sausage mixture along one edge, roll tightly, and seal edges by pressing together and crimping with a fork.

Slice each roll into bite-sized pieces and apply the beaten egg over the tops for a golden color.

Arrange the rolls on the baking tray with space in between and bake for 20-25 minutes until golden brown.

Allow to cool slightly on a wire rack and serve warm with spicy mustard or cranberry sauce.
