Place the slices of ham on top of each other and dice them finely. Beat the eggs in a large bowl. Pour in the milk, season with salt and pepper and whisk it smooth with a whisk.
Cut the slices of bread into large cubes. Heat half of the fat in a large coated pan. Add the bread cubes and fry them crisply while turning. Divide the bread cubes among 4 plates.
Heat the rest of the fat in the coated pan and fry the diced ham briefly in it. Add the peas without defrosting, steam them for 2-3 minutes, stirring more often. Then add the eggs and let them fry at low heat.
Use a spatula to push the egg mixture from the edge of the pan to the middle in large flakes until everything has set.
Spread the scrambled eggs over the bread cubes. Wash the chives, shake them dry and cut them into rolls with scissors directly above the scrambled eggs.
