Pour bread into a large skillet and drizzle with 1/4 cup olive oil, working in batches if necessary. Cook and stir bread over medium heat, adding more oil as needed, until bread cubes are golden and crispy on the outside, 7 to 12 minutes.

Sprinkle Parmigiano-Reggiano over the top of the bread cubes; cook and stir until cheese is melted onto bread, and bread is crispy on the outside but still chewy on the inside, 3 to 4 minutes more. Cool completely.

Combine tomatoes, red wine vinegar, extra virgin olive oil, garlic, sugar, salt, and black pepper together in a bowl until well-mixed. Cover bowl with plastic wrap and let sit at room temperature until flavors combine, about 20 minutes.

Toss basil into tomato mixture; add bread cubes and stir. Let salad sit at room temperature 3 to 4 minutes; if the liquid is completely absorbed, add more vinegar and extra virgin olive oil to taste. Season with salt and black pepper.
