This is standard tomato salad in Croatian households. It is so simple that I was not sure if it is necessary to submit it. Anyway, it is a part of Croatian usual meal, so, that is how it goes.
- Cut onion into thin rounds. Cut tomato into thin pieces, or into 1/8 parts.
- Put that into a salad bowl; add vinegar, olive oil, water, salt, pepper and marjoram. Mix, cool it for a while and serve.
