Omani cuisine revolves around rice. The morning meal is not significant, often consisting of bread or leftovers from the day before, and tea. The main meal of the day is in early to mid-afternoon. It is generally a large dish of rice with a thin sauce often based on tomato or tomato paste and meat or fish. Pork does not exist in the Omani diet as it is prohibited by Islam.
