Place the goat cheese, yogurt, herbs, salt, garlic powder and crushed red pepper in a food processor. Blend until combined, then with the processor still running, drizzle in the olive oil. You may need to scrape down the sides a few times to make sure everything is thoroughly mixed. Taste and season additionally if needed. Serve with extra pepper flakes on top. This will stay fresh sealed in an air-tight container in the fridge for a few days.
