While oven is preheating, cut ciabatta into bite-sized pieces.
Line a baking sheet with parchment paper. Spread ciabatta pieces out on the parchment paper and add pesto on top. Using your hands, toss ciabatta until evenly coated with the pesto.
Place in the oven and bake for 10 minutes, flipping halfway.*
Remove from the oven and allow to cool. Store in an airtight container for 5-7 days.
Notes
*After the 5 minute mark, keep a close eye on them to make sure they don't burn.
