i love eating all types of hamburgers,  A hamburger, beefburger or burger is a sandwich consisting of one or more cooked patties usually made from ground beef
I love hamburgers too! they are my fave, What kind of toppings do you usually put on yours? 
i usually only put onion chesse and tomatoes,  The patty may be pan fried, barbecued, or flame broiled
I like mine flame broiled, it tastes so much better that way. When was the burger invented anyway? 
The term "hamburger" originally derives from Hamburg, Germany's second-largest city but im not sure where it was invented
Oh wow it came from Germany! I had no idea, I always thought it was purely an American food. 
A hamburger topped with cheese is called a cheeseburger and that is my favorite burger
