A burger is another meal which lends itself well to being served family-style.  

Why spend time building stacks when you can set everything out on the table and have the family do the work? That way everyone gets to make up their burger in the way that suits them. 

And if your child isn’t sure about the patty, how about making up a tiny burger for them to explore? A tiny burger is more approachable than cutting a piece off a full sized burger.
