01 - Heat 2 tablespoons oil in a large skillet over medium heat. Add onions and sauté for 2–3 minutes until softened and translucent.
02 - Stir in garlic, ginger, and green chili. Cook for 1 minute until fragrant, being careful not to burn the garlic.
03 - Add ground beef to the skillet. Cook, breaking up meat with a spoon, until browned and cooked through, approximately 6–8 minutes.
04 - Stir in cumin, coriander, cinnamon, cardamom, cayenne, salt, and black pepper. Cook for 2 minutes to allow spices to meld with the meat.
05 - Remove from heat. Stir in chopped cilantro. Let filling cool completely to room temperature before assembling to prevent soggy wrappers.
06 - Place a spring roll wrapper on a clean surface. Spoon 1.5 tablespoons of filling near one corner. Fold into a triangle, tucking in the sides as you fold, and seal the final edge with water. Repeat with remaining wrappers and filling.
07 - Heat oil in a deep pan to 350°F. Fry sambusas in batches for 2–3 minutes per side, turning once, until golden brown and crispy. Drain on paper towels.
08 - Serve hot immediately, accompanied by lemon wedges, tamarind chutney, raita, or hot sauce for dipping.
