Heat 2 tablespoons of olive oil in a skillet over medium heat. Add the finely chopped onion and sauté for about 5 minutes, stirring occasionally, until the onions are softened and translucent.

Stir in minced garlic, grated ginger, ground cumin, ground coriander, ground cinnamon, and ground turmeric. Cook for an additional 1-2 minutes until the spices become fragrant.

Add your choice of ground beef, lamb, or chicken to the skillet. Cook for approximately 5-7 minutes or until the meat is completely browned and no pink remains.

Mix in optional ingredients like peas, raisins, chopped cilantro, salt, and pepper to taste. Allow this mixture to cook for another 2 minutes, then remove from heat and let cool.

While the filling cools, set out your spring roll wrappers or samosa pastry sheets and cut them into squares or triangles.

Take a spoonful of the cooled filling and place it in the center of each wrapper. Fold the wrapper and moisten the edges with water to seal.

In a frying pan, heat vegetable oil over medium-high heat until it reaches about 365°F (170°C). Fry sambusas for approximately 3-4 minutes per side until golden brown and crispy.

Remove the fried sambusas from the oil and transfer them to a plate lined with paper towels to drain excess oil. Serve them warm alongside your favorite dipping sauce.
