MAKE THE FILLING
To a pan over medium heat, add the olive oil and butter. Then add in the jalapenos and garlic and saute for 2 to 3 minutes.
Add in the minced chicken along with the salt, coriander, oregano, chili powder, paprika, onion powder, ginger, and black pepper. Mix together.
Saute the chicken until it's browned, about 6 to 7 minutes.
Optional, add a small splash of chipotle adobo paste for a smokey flavor.
Once the chicken is fully cooked, add in cilantro and mix together one last time before taking off the heat.
Allow the chicken filling to cool completely and then add the shredded mozzarella. Mix together.
ASSEMBLE AND BAKE
Preheat oven to 400°F.
Cut each pastry sheet into four equal pieces. Brush all four edges with egg wash.
Add a generous amount of chicken filling along one side. Then fold the puff pastry over the filling and press the edges down to help seal it and then transfer to a tray lined with parchment paper.
Take a fork all around the four sides, pressing down well to shut it tightly.
Brush the tops with egg wash, make 3 slits along the top, and then sprinkle with sesame seeds and/or black seeds.
Bake at 400°F for 20 to 25 minutes until they’re golden brown all around and fully cooked through.
