Clean and wash broccoli and cut into florets. Peel and chop the stalk. Wash and peel the carrots and cut them lengthwise into slices with a peeler. Steam broccoli in a little salted boiling water for eight minutes.
Add the carrots in the last three minutes and cook until done. Drain vegetables, collect vegetable water and measure 1/8 litre. Wash meat, dab dry and season with salt and pepper. Heat oil in a pan and fry the escalopes on each side for three minutes.
Dice butter. Heat vegetable water in a pot and stir in sauce powder. Bring the sauce to the boil and gradually add butter over a low heat. Wash the chervil, dab dry and chop finely, except for a little to garnish.
Stir the chervil into the hollandaise. Arrange cutlets and vegetables on a plate and pour the hollandaise sauce over them. Serve garnished with chervil.
