Preheat oven to 350F
In a bowl, toss the cubed bread with olive oil (see notes for a lighter version). If using a different quantity of bread, just lightly coat the bread in olive oil.
Sprinkle with a generous pinch of salt and pepper and any optional additions.
Spread in a single layer on a sheet pan.
Bake 10-12 minutes, give a stir and continue baking until golden, another 3-5 minutes.
Let cool completely. Store in a sealed container for up to 2 weeks.
