Preheat oven to 400° F. Prepare two baking sheets by lining with parchment paper or non-stick foil.
Add ground beef to a skillet over medium-high heat. Cook and crumble until browned then drain grease if needed. Add chili powder, garlic powder, onion powder, ground cumin, salt, pepper and taco sauce. Stir to combine well then cook for 5-10 more minutes. Remove from heat.
Add egg and water to a small bowl then stir to combine well. Unfold then lay a sheet of puff pastry on a lightly floured flat surface then brush lightly with egg mixture.
Add half of the ground beef mixture to the puff pastry sheet and spread to edges. Sprinkle with half a cup of shredded cheese. Roll up tightly like cinnamon rolls then cut in half inch pieces.
Lay flat, cut side down, on baking sheet. Repeat with other puff pastry sheet.
Bake for 15 minutes or until puffed and lightly golden brown. Serve with lime crema.
To make lime crema, add sour cream, lime zest, lime juice, garlic and salt to a bowl and stir to combine well.
