"Create a gluten-free, dairy-free Greek Village Pasties recipe for 12 pasties, using imperial units, suitable for a beginner cook and a household of 3 with moderate budget concerns. Keep it quick and easy (15-30 min active time if possible), minimal processing, and aligned with a low-inflammation rotation diet. Include seasoned ground beef, potatoes, rice, spinach, Kalamata olives, dairy-free feta substitute, lemon, dill, oregano, and parsley. Provide a flaky gluten-free pastry and include an optional dairy-free tzatziki or warm lemon herb sauce. Avoid gluten, dairy, nuts, shellfish, and corn. Use imperial units only."
