Peppers can be cut in half and cored, seeded, and set aside after removing the tops.
Medium heat should be used to heat the oil in a large frying pan. In a saucepan, cook the onions and garlic for 3 minutes, or until the onions have started to wilt. After adding the turkey to the pan, cook it for 7 minutes or until it has lost its pink color. Season rice with seasonings, add Parmesan cheese and add ¼ cups of tomatoes (reserve the rest). Ensure that the mixture is well heated by stirring well and cooking for a few more minutes. Depending on the taste, salt, and pepper should be added. Place the mixture carefully inside the pepper cavities.
The remaining tomatoes should be combined with the water in a large pot. Place the mixture in a saucepan and heat over a low flame until it simmers. The peppers should be placed upright in the pot. After the peppers are tender, cover them with a lid and cook them on low for 25 to 30 minutes.
The sauce should be spooned over the peppers and extra Parmesan cheese may be sprinkled on top.
