Packed Lunch Ideas -Gluten Free and Dairy-free - please help!

[ChateauRouge]

DD is suffering from a really bad flare-up of IBS, and cannot currently tolerate wheat or dairy products [weep]

Please could someone give me ideas as to what on earth I can put in her packed lunches? I'd almost got my head round gf, but dairy-free too? I am clutching at straws, as everything seems to have dairy in somewhere.

She's got a decent palate, and will try anything. She does have quite a big appetite, as she's growing, and is pretty active generally. She's 12, just going into Y8.

Thanks!

Thank you, we'll slowly introduce things one by one (she was pretty gutted about stone fruit and mushrooms!) to see what is setting her off. But I'm just over the moon with the improvement, it's been so hard for her the past few months.
I really appreciate you responding
