Onions peel and cut into cubes. Heat the oil in a pan and fry the onions in it. Add the vegetables and fry for 5 minutes, turning them over. Season with salt and pepper.
In the meantime, cook the eggs in boiling water for about 9 minutes. Deglaze the vegetables with cream and stock, stir in the pesto and let everything simmer for 10 minutes. Stir in sauce thickener and bring to the boil again.
Drain eggs, quench, peel and halve. Arrange vegetables and eggs in a bowl and serve garnished with parsley and oregano as desired.
