Step by step

Cut the bread roll in half

Tips
If you want you can substitute beef for the chicken or turkey burgers. And you can also add a slice of cheese: the overall result will of course be heavier and rather more indulgent!
Trivia
The burger is, originally, simply a patty of minced beef. But this little beef 'steak' had such good fortune and popularity that today when one talks about a hamburger one immediately thinks of it in a bread roll!
