Healthy snacks I fed DD at that age were:
- cheese
- zucchini slice
- raw or cooked beans

Lunch I give yoghurt and a sandwich and mix up the fillings sometimes....you could give her some vegies.....I'm pretty bad at variety....hope these suggestions help. Once she's a little older options really open up but when they're little it's kinda tough. Just give her tastes of lots of things. DD2 often gets a bit of whatever DD1 is eating. Ham's another good one
