Clean the vegetables, cut them up, and keep them in separate bowls because they go into the pan one after another.
Clean the small cuttlefish and wash the mantis shrimp (or shrimp).
Fry the mantis shrimp in oil, and when they are done, remove them and set aside.
Sauté the spring garlic and the tomato, then add the other vegetables - the green beans, peas and artichokes - without burning them.
When the vegetables have browned, add the small cuttlefish and cook for about 2 minutes, stirring constantly. Then pour in 3 parts water to 1 part rice, and note the water level in the pan.
Cook over medium heat for 30-45 minutes, until the vegetables are tender.
Top the water up to the original level, add the rice, saffron and mantis shrimp, spread evenly, and season.
Cook for about 20 minutes, until the rice is done.
