1. Cook your risotto rice in salted water.
2. Once cooked, mix the rice with the 2 eggs, butter, and let it cool.
3. In a pan, sauté the onion with olive oil. Add the ground meat, salt, and cook for a few moments.
4. Pour in the red wine and let it evaporate.
5. Meanwhile, prepare the tomato paste by diluting it in about 180 ml of water, then add it to the ground meat and cook for about 20 minutes over low heat.
6. Cook your peas and mix them with the meat.
7. The rice has cooled, we can now shape the arancini:
Take a handful of rice and lightly crush it. Form a hollow to place some meat mixture and a few pieces of mozzarella. Cover with rice and shape the arancino. Repeat the process as many times as necessary. Dip all the arancini in the beaten eggs, then in the breadcrumbs. Fry in hot oil.
8. Place the arancini on absorbent paper and let them cool down.
