“God raised him on the third day and made him to appear, not to all the people but to us who had been chosen by God as witnesses, who ate and drank with him after he rose from the dead.”
Based on his personal experience, Peter could have finished this sentence any number of impressive ways. He could have said, “God made him appear to us ... who saw with our own eyes the rolled-back stone and the empty tomb,” or “... who witnessed him perform miracles,” or “... who were shown the marks of his crucifixion in his hands and his side,” or even “... who saw him taken bodily into heaven and heard the testimony of angels about it.”
Instead, he talks about sharing food with the risen Christ: “God made him appear to us who ate and drank with him.”
