Boil the carrots, potatoes, and green peas in water for 10 minutes.
Heat the oil in a pan on a medium heat and sauté the green onions and the garlic.
Mash the boiled vegetables to form a paste and add them to the pan.
Add the coriander, cumin, Arabic spice, cayenne pepper, salt and black pepper to the vegetables and mix well.
Spoon a small amount of the vegetable mix onto a rectangular sheet of sambosa pastry and fold it into a triangle shape.
Fry the sambosa until golden and serve hot.
