1 lb (≈ 450 g) ground beef (80/20)
1 small onion, finely diced
2 cloves garlic, minced
1 tbsp tomato paste or 2 tbsp ketchup
1 tsp Worcestershire sauce
½ tsp paprika
Salt & freshly ground black pepper, to taste
½ to 1 cup shredded cheese (cheddar, American, mozzarella, or blend)
Dough or puff pastry (enough to cut 8 rectangles)
1 egg + 1 tbsp water or milk (for egg wash)
Optional: diced jalapeño, cooked bacon bits, vegetables
Preheat oven to 400°F (200 °C). Line a baking sheet with parchment.
In a skillet over medium heat, cook onion until translucent (2–3 min). Add garlic, cook 30 sec. Add beef, break up and cook 6–8 min until no pink remains. Drain excess fat.
Stir in tomato paste (or ketchup), Worcestershire sauce, paprika, salt & pepper. Simmer until mixture is just thickened. Let cool slightly.
Roll dough and cut into 8 rectangles. Place 2–3 tbsp beef mixture on half of each rectangle. Top with cheese.
Fold dough over filling, seal edges with fork, vent top with slits. Brush with egg wash.
Bake 20–25 min until golden brown and crisp. Cool 5 min before serving.
