Peel the onions, core the peppers and cut into strips. Wash the strawberries and remove the stalk. Then cut everything into fine slices using the gourmet slicer.
Juice the lime and make a dressing with olive oil, a dash of vinegar and the chopped herbs and pour over the slices of salt and pepper as required.
Finally, fold in two tablespoons of the spicy sumach.
The salad should sit in the refrigerator for a few hours before consumption.
