Prepare the salad: In a large bowl, mix tomatoes with olive oil, garlic, vinegar, basil, salt, and pepper. Set aside.

Prepare the croutons: Preheat oven to 350 degrees Fahrenheit. Cut bread into cubes and toss with oil, directly on a baking sheet. Spread in a single layer and sprinkle with garlic powder. Bake about eight minutes, until golden brown.

Just before serving, toss salad once more and add croutons.
