"Create a French Canadian Tourtière Pasties recipe inspired by Québec meat pies, allergy-friendly and suitable for a household of 3. Must avoid gluten, dairy, nuts, shellfish, and corn. Use minimal processing, low-inflammation-friendly ingredients, and keep it beginner-friendly and quick/easy where possible. Use fresh herbs and wholesome ingredients instead of onions, garlic, or warm baking spices. Include ground pork and beef, potatoes, mushrooms, celery, and apple in the filling, seasoned with sage, thyme, and parsley. Wrap in a flaky gluten-free pastry. Include an optional sauce choice between a Rustic Country Gravy and a Maple Dijon Herb Sauce. Use imperial units only. Make sure the recipe is accurate, cohesive, and formatted as a complete recipe with prep/cook/total time, servings, ingredients, instructions, freezer instructions, and cook's tips."
