- Trim off asparagus ends. In a shallow dish, stir together soy sauce, olive oil, garlic and thyme. Add asparagus and cover. Refrigerate for 1 hour.
- Preheat oven to 350ºF and line a baking sheet with parchment paper. Drain marinade and discard.
- Open dough and cut into 8 – 5 inch squares. Place on baking sheet. Place a slice of mozzarella on each piece of dough. Add 5-6 asparagus spears. Overlap two corners of dough to bundle asparagus and brush with egg. Sprinkle each bundle with sesame seeds. Bake 20-22 minutes, until puff pastry is golden brown. Serve hot.
