Toss bread cubes in the bacon drippings. Sear the halved grape tomatoes in 2 tablespoons of oil, cut side down, until caramelized about 5 minutes, set aside.
Combine red wine vinegar, salt and pepper in a bowl, slowly whisk in olive oil in a thin stream until emulsified.
Combine all tomatoes, bread, bacon, and lettuce and dress with vinaigrette, toss well, garnish with mint and basil and serve.
