Cook the pasta according to the instructions on the package and let it cool.
Meanwhile, peel the cucumber and grate it into small strips with a slicer. Collect in a small bowl and season with salt. Let stand for about 10 minutes so that the cucumbers can water. Drain the water and squeeze out the cucumbers a little more by hand.
Wash the spring onions and cut into small rings. Cut the feta into small cubes. Open the can of corn and pour off the juice. Mix together yogurt, mayonnaise, cream and lemon juice.
Now add everything to the pasta and stir slowly. Season to taste with salt, pepper and sugar.
Chill the salad before serving and leave it to stand for 2-3 hours. It tastes very good the next day and has been a hit at every barbecue party so far.
