Preheat the oven to 300° F. Slice the loaf in half or lengthwise, so you can get at the soft bread inside - do not use the crust. With your fingers, tear away pieces of bread that are approximately 1/2" to 3/4" in diameter. Place them in a large bowl and whisk the oil, salt, pepper and garlic together in the bowl and toss until they are all evenly coated. Spread them on a large baking sheet and place in the oven for 15 to 20 minutes, stirring them ever 5 minutes, until they are golden brown.
