Preheat the oven to 180°C (350°F). Slice a baguette into 1 cm thick pieces and arrange them on a baking sheet. Drizzle with 2 tablespoons of olive oil and bake for 10-12 minutes, or until the bread is golden and crispy.
In a mixing bowl, combine 200 grams of finely chopped tomatoes, 100 grams of pitted and chopped black olives, 1 finely chopped small red onion, 2 minced garlic cloves, 10 grams of chopped fresh basil, and 10 grams of chopped fresh parsley.
Add 2 tablespoons of olive oil, 1 tablespoon of balsamic vinegar, salt, and pepper to taste. Mix well and let the mixture sit for 10 minutes to allow the flavors to meld.
Spoon the tomato and black olive mixture onto the toasted baguette slices and serve immediately.
