This is Robbie's favourite glass container to re-heat his Jumbo size meals. The glass containers complement our durable bpa-free plastic containers on our Paleo Meal Plan (reminder: which need to be returned! ) to re-heat your meals perfectly. Pro Tip: Please, please please... re-heat your meals in a glass/ceramic container in an oven (not a microwave-oven), and they will be crispier, juicier and 3x tastier! Robbie on use of plastic: Our durable and re-usable plastic containers are 100% micro-wave safe and bpa-free, but at Paleo Robbie we only use plastics for storing non-acidic food at chilled temperatures. When re-heating you should use glass, ceramic or stainless containers or plates only.
