Fish salad with fried onions

Ingredients:

1 can any fish in own juice or in oil
3 hard-boiled eggs
2 large onions
1 tbsp vegetable oil
1 tsp sugar
3 tbsp mayonnaise
Crushed black pepper on taste

Method:

Take egg yolks and crush them.
Shred egg whites.
Add oil in a large skillet, heat and add thin onion rings to the skillet, pour sugar over it and fry until the onion rings are golden. Cool the onions.
Put the fish in a dish; press it with forks until you have small pieces of fish about same size.
Pour egg yolks over it.
The next salad layer is the onion rings, and then a layer of whites mixed with mayonnaise.
Pour with black pepper (no salt!)
Let sit 30 minutes, and serve.

Note:

Optionally, you can add two more layers to this salad:
shredded cheese and very cold shredded butter or margarine.
And, of course, you can use thin pieces of boiled or smoked fish.
Generally, layered salads, or salads-cocktails are very popular in the Nobility's cuisine.
