Heat a small saucepan over medium-high and add 1 Tbsp olive oil. Add torn sourdough and a dash of salt and pepper. Toss bread until completely coated in oil and seasoning. Cook for five minutes, tossing the bread often so it evenly toasts on all sides. Remove from heat and transfer to a bowl.
Add tomatoes, mozzarella, remaining 1 Tbsp olive oil, and white beans to the bowl and toss to combine. Garnish with basil leaves and season with salt and pepper.
Enjoy right away.
