When we look at the Prophet Muhammad PBUH life, we find that Prophet SAW led a very simple life, especially in his diet. Prophet SAW ate what ever was available and did not criticize any food. If the food was not likely, the Prophet SAW did not east it with out criticizing it.
Umm e Hani reports, “The Prophet SAW came to my house once and asked if I had anything to eat. I said: ‘No, I have nothing except dry bread and vinegar.’ He said: ‘Bring it. Blessed is the house that has vinegar to go with bread.’” (Related by Al-Tirmidhi.)
Here are some Ahadith about the Sirka which Prophet SAW used it in his meals.
