It has come to my attention that in the book "Green Eggs and Ham", the property "green" is applied to both the eggs and the ham. How can I achieve this effect (green ham) at home? I have years of green eggs + normal ham to make up for ;) 
When I did this as a kid with my mom, we just put food dye (the same we put in the eggs) on the slices of ham.  As someone who has tried this though, I have to strongly recommend you don't. While it's easy to get around the fact that the eggs you're about to eat are green, ham that's green just doesn't look right. It was a struggle to eat it even though I knew it was only food coloring.  My dad wouldn't even touch it because it looked so wrong.
