Allah is pleased when you praise Him for a meal
إِنَّ اللَّهَ لَيَرْضَى عَنِ الْعَبْدِ أَنْ يَأْكُلَ الْأَكْلَةَ فَيَحْمَدَهُ عَلَيْهَا، أَوْ يَشْرَبَ الشَّرْبَةَ فَيَحْمَدَهُ عَلَيْهَا
Inna-llaha la-yarda 'ani-l-'abdi an ya'kula-l-aklata fa-yahmadahu 'alayha, aw yashraba-sh-sharbata fa-yahmadahu 'alayha.
"Allah is pleased with the servant who eats a meal and praises Him for it, or drinks a drink and praises Him for it."
Narrated by Anas ibn Malik. Sahih Muslim 2734
A short reflection
Gratitude this small earns the pleasure of Allah: a sip, a bite, and alhamdulillah. The blessings you want to keep are held by thanking Him for the ones already in your hand.
