Clean the leek, wash it. Cut the upper green third of 2 sticks into fine strips. Cut the rest of the leek into pieces of about 5 cm and cook covered in boiling salted water for 12-15 minutes. Lift out and drain. Blanch the leek strips in salted water for about 2 minutes. Drain
Cut the ham into fine cubes. Chop the walnuts, except for a few halves for garnishing. Mix cream cheese, milk and egg. Fold in ham, nuts and leek strips. Season to taste with pepper, sweet paprika and possibly salt.
Place the leek pieces in a greased casserole dish and spread nut mixture on top. Bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 25 minutes. Sprinkle the rest of the nuts on top about 5 minutes before the end of the baking time. Wash the chives, chop finely and sprinkle over the top. Goes well with mashed potatoes
Nuts provide up to 25 % high quality protein. So you can leave meat out for a while
