So, we have recently tried praying after a meal or segueing with it into our family worship time. Sometimes, we have thanked God for the food at our bedtime prayers.
Of note, I flipped through Frank Schaeffer's book, Crazy for God, passing the airport recently (I don't recommend; in some respects it seems like a type of dancing on his dad's grave). One of his "fondest" memories with his dad, Francis, is when they would take trips together and purposefully neglected a meal time prayer. I strongly recommend Edith Schaeffer's well-written tome of the history of their ministry, L'Abri.
