In a small bowl, add the ground beef. Make a well in the center and add the egg, uncooked rice, black pepper and salt to taste, breadcrumbs, a few drops of Maggi seasoning sauce, and finely chopped mint. Mix everything together until well combined, then set aside.

Wash the vegetables thoroughly. Cut the carrots, potatoes, and zucchini into cubes or pieces. Sauté them in a large pot. In a blender, blend the tomatoes with the piece of onion, 2 garlic cloves, and 2 or 3 chipotle peppers in adobo sauce, depending on how spicy you want it. Add water, then pour the mixture into the pot with the sautéed vegetables. Season with salt and bring to a boil.

Once the broth starts boiling, shape the ground beef mixture into small balls and add them to the broth. Continue until all the meat is used. Cover and let it boil well. Check for salt, cover again, and once it has boiled thoroughly, turn off the heat. Serve and enjoy.
