Place the chicken liver in a frying pan, fry over medium heat for 15 minutes, then add the onion, cut into half rings, and chopped garlic.
Cool the fried chicken liver, then mince it until it has a uniform consistency. Place the resulting mass on the film and smooth it out.
Grate the cheese and chicken eggs. Mix to obtain a uniform consistency, add salt and pepper to taste. Spread the resulting mixture as a second layer.
Roll the film so that it forms a roll, carefully roll it from the ends and shake it several times so that it becomes more dense. Put it in the refrigerator for at least 1-2 hours, or better yet, overnight.
