Bruschettas are of Italian origin and are traditionally prepared by grilling a toast over a wood fire in order to infuse the smoky taste.
I have however, used a charcoal barbeque for making these you can also use the electric one if you like or even an oven will do just as well.
You can also try other bruschettas like Pesto and Roasted Red Capsicum Bruschetta or Pear and Brie Bruschetta .
