Help with 2.5 year old night time wanderer?

What's the best way to stop my 2.5 year old from wandering around the house at 3 am and eating lunch meat out the fridge? My daughters didn't do this when they were that age...it's kinda freaky because he will go get the lunch meat and stand by my side of the bed and eat it. I wake up, and the container is on my bedstand.
