We try and vary the items daily and fill them with colours and textures to appeal to my girls. Since using them they come home 90% of the time completely empty and tummies full.
I don't have to fiddle with a pile of different containers to wash and dry and can put the whole thing in the dishwasher. We have the rover and launch and love them both.
Here are some of our meals...oh and Piper modelling the insulated bag!
hummus, almonds, berries, veggies, grain free cookies, quinoa crackers
veggie sticks, avocado sushi, coconut yogurt, japanese tofu, fruit, bagel chips
