this recipe

   • Cook, stirring occasionally, for 15-20 minutes until golden and caramelized.
   • Stir in sugar and balsamic vinegar, cooking for an additional 2-3 minutes. Remove from heat and let cool.

   • In a large bowl, combine sausage meat, caramelized onions, thyme, and garlic powder. Mix until well combined.
3. Assemble the Sausage Rolls:
   • Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
   • Roll out puff pastry sheets and cut into rectangles (approximately 4×6 inches).
   • Spoon the sausage mixture lengthwise onto each rectangle, leaving space on the edges.
   • Fold the pastry over the filling and seal the edges by pressing with a fork. Place seam-side down on the prepared baking sheet.
4. Egg Wash and Garnish:
   • Brush the tops of the sausage rolls with beaten egg. Sprinkle with sesame seeds if desired.
5. Bake:
   • Bake in the preheated oven for 25-30 minutes, or until the pastry is golden and the filling is cooked through.
