You can make croutons with any bread but it works well with thick white bread that is stale or dry. Take 2 slices, cut off the crusts and then cut into cubes. Put the bread in a bowl and drizzle over 2-3 tablespoons of oil and season with salt. Stir well then transfer to an oven tray in an even layer. Bake for 8 to 10 minutes at 180C/350F. You could also fry them if you prefer.
