Cut off the cress and whisk together with the chives, eggs and mineral water and season with salt, pepper and nutmeg.
Now melt the butter in a coated pan and pour the egg mixture into it. Then let them set at MEDIUM heat and always push them from the outside to the inside after a while.
In the meantime, halve the rolls, brush with tartar sauce and top with a lettuce leaf.
Now cut the tomatoes into wedges and distribute them on the rolls together with the scrambled eggs.
