Preheat the oven to 350 degrees Fahrenheit.
In a medium sized frying pan, saute the onions with 2 tablespoons of oil over medium heat for 10 minutes or until lightly golden.
Add garlic and saute for 2 additional minutes. Set aside.
In a large mixing bowl combine the sauteed onions, ground meat, fresh herbs, spices, salt, pepper, carrot, pear, barberries, flour and the 2 lightly beaten eggs. Mix well.
If the meat mixture is too sticky and wet feeling, adjust by adding more flour.
Lightly grease a loaf pan and begin by layering half of the meat mixture in the pan.
Place the 3 hard boiled eggs in the pan and lightly press down.
Add the remaining meat mixture and press lightly to combine the two layers.
Place the meatloaf on the center rack of the oven and cook for approximately 1 hour. The internal temperature should reach 160 degrees Fahrenheit.
Once lightly cooled, carefully remove the meatloaf from the pan and place on a serving platter.
Brush the meatloaf with grape molasses and sprinkle with pistachios.
Serve with Persian flatbreads or steamed basmati rice.
