Preheat the oven to 400 degrees. Place the block of feta in a baking dish and drizzle with olive oil. Bake for 10 minutes. Turn the broiler on in your oven and broil for 2 to 3 minutes until golden on top.
Remove the baking dish from the oven. You can transfer the feta to a plate or serve it in the dish. Cover it with the chili crunch. Serve immediately with crackers or pita chips.
