01 - Heat 2 tablespoons vegetable oil in a large skillet over medium heat. Add finely chopped onion and sauté for 2 to 3 minutes until softened and translucent.
02 - Stir in minced garlic, grated ginger, and chopped 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 spatula, until browned and cooked through, approximately 6 to 8 minutes.
04 - Stir in ground cumin, coriander, cinnamon, cardamom, cayenne pepper, salt, and black pepper. Continue cooking for 2 minutes to allow spices to meld with the meat.
05 - Remove skillet from heat. Fold in chopped fresh cilantro. Transfer filling to a bowl and let cool completely to room temperature before assembling.
06 - Place a spring roll wrapper on a clean work surface. Spoon approximately 1.5 tablespoons of cooled filling near one corner. Fold into a triangle shape, tucking in 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, cooking 2 to 3 minutes per side or until golden brown and crispy. Remove with a slotted spoon and drain on paper towels.
08 - Serve hot with lemon wedges, tamarind chutney, raita, or hot sauce for dipping.
