Briefly toast the sesame seeds in a non-stick frying pan until they are golden-yellow to slightly brown in color.
Peel the cucumber, quarter it lengthways and cut into small pieces. Do the same with the avocado. Chop the tomatoes and mushrooms, dice the onion. Cut the chives into coarse rings and chop the parsley. Add the cress and mix everything well in a bowl.
Now pour the sesame oil and vinegar over the salad and season with salt and pepper. Pour in some water and mix everything well again.
If you like it a bit spicier, you can also add a little (approx. 1-2 teaspoons) Sambal Olek.
Let the salad stand for 5-10 minutes, enjoy with warm flatbread and a light white wine.
I only estimated the ingredients for the dressing, maybe change to taste.
