Separate the white and green parts of the spring onions and garlic.
Chop the greens finely and set aside.
In a pan over medium heat, sauté the white parts of the onions and garlic for 2-3 minutes.
If using lamb heart, add it to the pan and cook for 8 minutes.
Cut the liver into chunks and add it along with the garlic cloves.
Fry for 6-7 minutes, then add the green onion and garlic parts, cooking for one more minute.
Remove from heat and allow the mixture to cool completely.
While it cools, boil two eggs for 10 minutes.
Chop the dill and parsley finely.
Once the liver mixture has cooled, chop it finely (or use a chopper).
In a bowl, mix the chopped liver, fresh herbs, raw eggs, salt, pepper, and nutmeg.
Preheat the oven to 180°C (350°F).
Grease a loaf pan with butter or line with baking paper.
Add half of the drob mixture, place the boiled eggs in the center, and cover with the rest of the mixture, pressing it down gently.
Top with thin slices of butter.
Bake for 40 minutes, or until a toothpick inserted in the middle comes out clean.
Once done, let the drob cool in the pan, then refrigerate overnight.
The next day, remove from the pan, slice, and serve chilled or at room temperature.
