For those looking for a healthier version of Rogan Josh, there are several modifications you can make. Use lean cuts of meat like chicken breast or trimmed lamb to reduce the fat content. Instead of frying the onions, you can sauté them in a small amount of oil or even use a non-stick pan. Opt for low-fat yogurt or Greek yogurt to reduce the calorie content. Additionally, you can add more vegetables like spinach or cauliflower to increase the nutritional value of the dish. With these simple tweaks, you can enjoy a healthier version of Rogan Josh without compromising on taste.
