Mishkat al-Masabih 4180
Anas said:
A tailor invited the Prophet to a meal which he had prepared and I went along with the Prophet. He presented barley bread and soup containing pumpkin and dried sliced meat, and I saw the Prophet going after the pumpkin round the dish, so I have always liked pumpkin since that day. 

(Bukhari and Muslim.)
وَعَنْ أَنَسٍ أَنَّ خَيَّاطًا دَعَا النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِطَعَامٍ صَنَعَهُ فَذَهَبْتُ مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَرَّبَ خُبْزَ شَعِيرٍ وَمَرَقًا فِيهِ دُبَّاءُ وَقَدِيدٌ فَرَأَيْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَتَبَّعُ الدُّبَّاءَ مِنْ حَوَالَيِ الْقَصْعَةِ فَلَمْ أَزَلْ أُحِبُّ الدباءَ بعد يومِئذٍ
