A panzanella is at its core a bread salad. A crispy, crunchy, salad of toasted (or stale) bread tossed with fresh vegetables and a simple piquant vinegar-based dressing.
Toss the tomatoes with a teaspoon of salt in a bowl and set aside. Cook the pancetta over medium heat until crisp. Remove to a paper towel lined plate to drain, reserving the drippings in the pan.
Whisk together all of the ingredients for the dressing in a small bowl except for the oil. Slowly whisk in the olive oil in a steady stream until emulsified.
Combine all of the salad ingredients in a large bowl and toss with the dressing. You can serve immediately or allow to sit at room temperature for
30-60 mins before serving.
