I love hamburgers! I think I could eat them daily. Do you like hamburgers?
I like hamburgers.  There is much controversy over their first appearance.. 
Is there really? I didn't know that! What's the controversy about?
It is over their origin. Because the ingredients are beef and bread. 
Oh, wow. Have you ever tried a burger made from something other than beef?
Yes, I've eaten ground turkey, chicken, and pork burgers.  But they are usually made from beef placed inside a bread bun.  
That's usually how I make mine. How do you cook yours? I like to put mine on the grill.
I like them barbecued, baked or fired.
