"Create a make-ahead casserole lunch for 4 people with side dishes. It should be easy, quick-prep, and suitable for 2 vegetarians. Use only ingredients that fit the user's profile: low FODMAP, dairy/lactose-free except mozzarella and American cheese are allowed, legume-free, shellfish-free, corn-free, low sodium, minimal processing, no alcohol, anti-inflammatory, kidney- and heart-friendly, IBS/IBD-friendly. Tofu is okay. Noodles or other pasta are okay. No fresh produce. Avoid beef, poultry, shellfish, pork, and some fish such as sole for the non-vegetarian household member. Use imperial units only. Include a casserole plus simple side dishes, and keep it practical for meal prep."
