Cut baguette into 1/2" slices. Place in a single layer on a baking sheet. Brush lightly with 1 tablespoon of the olive oil. Broil bread slices for 1-2 minutes until lightly browned. Turn slices and repeat.
1 loaf baguette, 2 tablespoons olive oil
Place toasts in a basket or on your preferred serving dish.
Mix chopped tomatoes, with one tablespoon olive oil and add remaining ingredients. Stir until combined.
OPTIONAL: For a parmesan topped bruschetta, leave toasts on the baking sheet and spoon tomato mixture onto the bread. Sprinkle each with fresh Parmesan cheese and return to broiler for just a minute or two.
Notes
You can use any variety of tomato, but if you choose a very juicy variety, you'll probably need to drain off some of the juice before you add the remaining ingredients. Too much liquid can make the bruschetta soggy.
