We are veggie. ds (2.6) takes lunch to nursery, but we have to avoid all nuts and seeds due to a child there with allergies. So no peanut butter, houmous (sesame) etc. I also try and make sure there is always some protein. At the moment he is getting cheese and pickle sandwiches most days (with a bit of veg hidden in the pickle). Any suggestions to widen his diet at all?
