This is a stupid question but I'm sure someone has a brilliiant idea that I'm not thinking of. My kids are 4 and 2 and go to full day daycare. We currently send their lunch in a plastic "Easy Lunchbox" container, but they don't seal well enough to be spill proof.

So we've gotten in this habit of sending a yogurt or applesauce pouch every day, which is adding up to be so expensive! I know I could just send applesauce cups which would at least be cheaper, but does anyone have any better ideas? I'm worried if I just send applesauce in a tupperware I won't get it back.
