What can I cook for my fussy daughter?

My 13-year old daughter is a bit of a fussy eater. I want to do more hot pots,caroles,stews, stuff like that since it's getting into wintertime now. She can't eat peppers (allergic) cheese sauce (as in the sauce part of mac and cheese usually used in fish pies) She can't stand leeks, she can't eat tomatoes and she hates cheese on mashed potato. Although she loves mash potato. Please don't suggest any roast dinners as we save them for sundays only. She loves mash and gravy, she likes mild curries, she's ok with spinach and mushrooms. She LOVES sweetcorn and carrots and peas. Please suggest any ideas as they are welcome. Sausage dishes are ok but all suggestions must have some kind of meat with them otherwise my husband complains. No soups please. We are a family of 4. Please submit you suggestions and i will tell you if they are good or not. Thankyou! Oh, and she loves to cook but if she doesn't like her own cooking she acts just the same way as if i cook the meal. Thanks.
