Johannisbeeren (currants) are available in Migros - and with them you can make a delicious chicken salad.
Getting a really good roll also makes a difference - I have found that the ones at Coop on Silbernstrasse in Dietikon are very good (see picture)
What you need:
Chicken (rotisserie chicken - pre-made or bought is good)
1 red onion
1/2 -1 green apple
2-3 stalks of celery
1/2 cup of johannisbeeren
1/4 cup slivered almonds
Pull the stems off of the johannisbeeren and wash them.
Shred the chicken
Put all in a bowl and mix. Add the almonds (if desired) and then add enough mayonnaise to make everything stick together.
Put on a roll and enjoy with a side salad or chips. Nussli-salat and a tomato on top of the chicken mixture is also good
