Preheat oven to 425°F. Toss carrots with 1 1/2 tbsp olive oil on a baking sheet, and season with salt and pepper. Roast until carrots are caramelized, around 25 minutes.
In the meantime, heat a small pan over medium heat. Toss diced focaccia with 1/2 tablespoon olive oil in a bowl and transfer to pan, tossing frequently until toasty, around 5-7 minutes.
Transfer carrots to a serving dish and sprinkle with parsley, feta and toasted focaccia crisps.
Buon appetito!
