DS is in nursery, I send in breakfast, lunch, and two 'snacks' for every day. He also has a pot of plain whole milk yoghurt.
Breakfast is often a bit of scrambled egg and sausage and some peas, or a slice of bacon and broccoli, or quiche, or a sausage and cornmeal muffin... all home made, all things he likes. Lunch is usually a portion of a previous dinner that has been scooped off and frozen, so it could be lasagne, fish pie, anything like that with veg. There's alsways a few slices of fruit in there for both meals too, though that mainly gets thrown around I suspect
BUT! the snacks are ... well, I dunno if they're nutritionally very respectable. Animal crackers (those little biscuits), rice cakes, raisins, babybel cheeses or laughing cow cheese triangles...
I'm not too fussed and I'm not trying to competitively -lunchbox, but as we quite like cooking from scratch, I'd love some suggestions. He sometimes likes a banana mini-muffin... I can't send peanut butter any more, which was a big hit - What do people give their toddlers for snacks that aren't biscuits or rice cakes?
