This is a crispy sharp salad that sits well with barbecued meats.
1 Peel the cucumber and red onion and slice finely.
2 Slice ripe tomatoes crossways and layer the three ingredients onto a platter.
3 Splash over a moderate amount of cider vinegar, season with salt and pepper and leave to macerate an hour before serving.
If available, fresh oregano or marjoram sprigs make a nice garnish and flavour contribution.
