That's sounds like a good lunch.
We do sandwiches for lunch in our house, and dinner at 5pm, some snacks inbetween.
My dd is fussy, and it's rubbish about offering other foods, as we've done this, and she won't even taste. We have calm meal times too, never hectic, and we don't do the 'eat your dinner or no pudding', as it never works anyway.
My dd can live off sausages, chicken, ham, cheese, fruit, baked beans, radishes
, and bread/toast.
We had her weighed, as to me she looks slim, but she is tall, and the doc said she was in range. Think it's cos she's so active.
She's never hungry either. If she is, she asks for a sandwich!
