Broil the liver to medium doneness or sauté in oil on both sides. Cool the liver completely. Brown the onions in a bit of hot oil.
You can process the liver mixture in one of two ways.
1. Grind the liver, eggs and fried onions in a meat grinder.
2. Process the liver in a food processor until minced. Add the remaining ingredients and process until blended. Add the seasonings. You can add a bit chicken broth if needed to reach the desired texture.
