Preheat oven to 375°F. Toss the bread with oil and spices, and arrange on a parchment-lined baking sheet. Bake for 15-20 minutes, flipping halfway. Keep a close eye on the croutons towards the end - they can go from perfect to burned very quickly. Once the croutons are baked, sprinkle with a little extra (or a lot extra) Everything But the Bagel Seasoning.
