Cut the leek into two equal pieces. Then cut the pieces into four equal parts. This results in 8 small leek sticks, each of which is then rolled into a slice of ham. Put everything in a baking dish. Mix a cup of cream with half a cup of water. Then add two teaspoons of instant stock and a little salt and pepper. Mix everything well and pour over the rolls and sprinkle with the grated cheese.
Put everything in the oven for about 20 minutes at 180 ° C top and bottom heat.
