My daughter just reminded me that one of her favourite snacks before supper is soup. I make homemade chicken or turkey broth and freeze it, and once a week or so I make a huge pot of soup for supper, and the leftovers go into the fridge and they snack from it the rest of the week. I make sure there's lots of protein and veggies in it, and usually some brown rice. I make a huge variety so that they don't get bored of it- gypsy, chicken and rice, kale and sausage, white bean and spinach, etc.
I make loads of soups for my daycare and my daughter loves them too. sweet potato, leek and potato, chorizo, veggie and mulligatawny. I'm hungry now
