The only options for substitutions are with our main line of weekly meals (https://www.petespaleo.com/collections/all/products/paleo-meal-delivery) and it's for no pork and no duck. If you choose no pork/duck, we will just double up on some of the other proteins from that week’s menu. Pete’s Paleo feels it is crucial to your health that you are eating a varied, seasonal menu. That’s what our menus are based and designed around. Don’t be afraid to try new things and find out how delicious they are!
