2 c. stock, or strained tomato liquid, or water, or a combination, warmed
1/2loaf (or more) day-old French or Italian bread, torn or cut in cubes
1/2c. torn or roughly chopped basil leaves.
Put oil in a large, deep saucepan or casserole and turn heat to medium. A minute later, add onion, garlic and dried chile, if using. Season with salt and pepper and cook, stirring, until garlic is fragrant and golden and onion begins to soften, about 5 minutes.
Add tomatoes and cook, stirring occasionally, until tomatoes break up, about 10 to 15 minutes. Add liquid, stir in bread and simmer for a minute more.
