Pre heat oven to 230c
Line 2 baking trays with baking paper.
Place butter in a small heat proof bowl and microwave for 30 seconds, or until melted, then add crushed garlic.
Meanwhile, remove crust from bread and cut into 2cm or 3/4 inch cubes - see note.
Place bread cubes in an even layer on baking sheets, and bake for 5 mins.
Remove cubes from oven (reserving baking paper) and place in a large heat proof bowl.
Slowly drizzle garlic butter on to cubes, mixing to coat as you go - I use a pastry brush for this - trying to get the cubes as well coated as you can.
Place cubes back on baking paper lined trays in a single layer, bake for 3-5 mins, depending on your desired amount of colour and crunch.
Remove from oven, toss lightly with herbs, serve immediately.
