"Create a dairy-free, wheat-free, corn-free unstuffed cabbage roll casserole inspired by traditional old-fashioned cabbage rolls. Use the linked recipe only as base inspiration for flavor profile and structure: cabbage, ground meat, rice, tomato sauce, onion, garlic, and warm seasonings. Make it beginner-friendly, quick/easy (15-30 min active time if possible), minimal processing, low-inflammation leaning, and suitable for a household of 3. Avoid all gluten, dairy, nuts, shellfish, soy, sesame, and corn ingredients. Use imperial units only. Include a clear ingredient list, simple steps, and a brief note for make-ahead/storage if appropriate."
