"Create a space alien themed recipe named 'Avocados and Aliens'. Make it fun and whimsical but still practical and tasty. Use ingredients that fit an omnivore household of 4, moderate budget, and average cooking time (30-60 minutes). No alcohol. Include imperial units only. The recipe should feature avocado prominently and have an alien/space-inspired presentation or naming for components. Provide a complete recipe with ingredients, instructions, prep/cook time, servings, and any helpful tips."
