Dry-fry the mince in a frying pan until brown and crumbly, stirring occasionally and breaking it up with a wooden spoon.
Add the onion, green pepper and garlic; cook, stirring occasionally, until softened. Stir in the herbs and spices; season to taste with salt and pepper. Add the tomato puree and mix well. Cover and cook gently for 10 minutes, stirring occasionally.
Place a little of the mixture on each tortilla and roll up. Secure with a cocktail stick. Heat the oil in a frying pan and then fry the rolls quickly until golden. Serve with your choice of accompaniments.
