I have been a What a Crock customer for a while now and I thought it couldn't get any easier than tossing a meal in the slow cooker and letting it cook its self but then I added liners to my last order. I read somewhere I could remove the liner and use it instead of Tupperware. So now I open a bag toss it in a slow cooker and go to work get home eat then tie a bag and toss it in the fridge. I don't have to cook, I also don't have to clean the slow cooker and I don't even have to dirty Tupperware. I love this company!
