"Create a gluten-free, dairy-free, nut-free, shellfish-free, corn-free Appalachian-style pasty recipe inspired by hearty farm kitchens. Use minimal processing, beginner-friendly steps, and quick-prep guidance where possible. Include a savory filling with ground pork, bacon, sweet potatoes, apples, mushrooms, celery, herbs, and a touch of maple syrup. Provide imperial units only. Make it suitable for a household of 3 with moderate budget concerns, and include freezer-friendly instructions plus one sauce option that is also free of gluten, dairy, nuts, shellfish, and corn. Keep the recipe accurate and practical."
