- Preheat your oven to 350 degrees F (175 degrees C). Take a baking pan and line it with parchment paper. 
- Cut the baguette into 1-inch (2.5 cm) pieces, and spread them out on the baking pan. Make sure that the pieces are evenly spaced out. 
- Bake the bread for about 10 minutes, or until golden brown. Remove from oven and let cool. 
- Meanwhile, prepare the dressing by whisking together all of the ingredients in a bowl. Set aside. 
- In a large salad bowl, combine the cooled bread pieces, tomatoes, cucumber, onion, garlic, olives, and basil leaves. 
- Pour the dressing over the salad and mix everything together gently with your hands or a spoon. Let sit for about 15 minutes so that the bread can absorb some of the dressing flavors. 
- 7 . Serve the summer panzanella salad at room temperature. Enjoy!
