I saw that the Prophet ﷺ put a date on a loaf and said: This is a thing eaten with bread (condiments).  

رَأَيْتُ النَّبِيَّ ﷺ وَضَعَ تَمْرَةً عَلَى كِسْرَةٍ فَقَالَ هَذِهِ إِدَامُ هَذِهِ  

A similar tradition has also been transmitted by Yusuf b. 'Abd Allah b. Salam through a different chain of narrators.  

عَنْ يُوسُفَ بْنِ عَبْدِ اللَّهِ بْنِ سَلاَمٍ مِثْلَهُ
