With just a little olive oil and some salt, Kelli Foster at The Kitchn suggests you can turn that hardtack into a batch of croutons on your stove top. Start by cutting up the scones into small cubes. Then heat two tablespoons of olive oil in a large frying pan over medium-high heat. Add the chunks to the pan, sprinkle on some salt, and toss so the oil coats all the pieces.
Once your croutons are toasted, they're ready to serve or store. If you have a big batch, you can keep some in the freezer for up to 6 months until you need them.
