Jesus served the disciples fish.

John 21:10-13

Jesus saith unto them, Bring of the fish which ye have now caught. 11Simon Peter went up, and drew the net to land full of great fishes, an hundred and fifty and three: and for all there were so many, yet was not the net broken. 12Jesus saith unto them, Come and dine. And none of the disciples durst ask him, Who art thou? knowing that it was the Lord. 13Jesus then cometh, and taketh bread, and giveth them, and fish likewise.
