For Family Home Evening, we ate foods that Jesus might have eaten:
You'll also notice we ate a little salad consisting of green peppers and tomatoes tossed with oil and vinegar and seasoned with sea salt and pepper. I have read that bell peppers and tomatoes were not available in the Middle East during the time of Christ, but it was still pretty yummy!
This post on Sabbath Meals gives a nice rundown on what Christ might have eaten during his life. And the Primary lesson "Jesus Christ Was a Child Like Me" gives some ideas for helping children identify foods that Christ might have eaten and things that he might have done as a child.
We also briefly talked about the Passover feast.
Since The Ten Commandments is one of my son's favorite movies, he was all over that.
