Put the eggs and milk in a bowl, stir well and season with salt and a few turns from the pepper mill. Cut the ham into thin strips and add to them.
Heat the butter in a frying pan and pour the mixture into it. Reduce the heat and stir carefully as soon as the egg begins to stagnate on the bottom of the pan. The scrambled ham is ready after 2-3 minutes.
Cut the leaves from the cress into the hot scrambled eggs and stir everything again.
