First, heat the butter or margarine and toast the oat flakes in it, stirring constantly. Be careful not to burn them.
When the oat flakes are toasted, add 1 l of vegetable soup. Add the garlic and parsley and bring to a boil.
While the soup is boiling, take the eggs to hand and drop them into the soup in batches, creating bite-sized pieces. The soup should be boiling at the time for the egg to firm up into chunks.
Once the egg is added, turn off the heat and simmer a little longer with the residual heat.
Arrange the soup and serve.
