"Create a fun, spooky avocado toast recipe called 'Nightmare on Avocado Toast' that looks like a dramatic horror-movie murder scene, but keep it food-safe and appetizing. Use ingredients and presentation to create a dark red 'blood' effect (for example, beet puree or tomato jam) and eerie garnish styling. Include imperial measurements, serves 4, moderate budget, and average cooking time (30-60 minutes). Provide clear ingredients and step-by-step instructions."
