These lip-smacking tacos typically consist of a sautéed vegetable filling that includes saffron, bell peppers, onions, and mushrooms, seasoned with Mexican spices such as cumin and chilli powder. The filling is then stuffed into warm tortillas and topped with fresh ingredients such as diced tomatoes, avocado, and cilantro. Saffron adds a unique flavour and a vibrant yellow colour to the dish, making it an exciting and delicious twist on traditional taco recipes.
