Yes, you can! Wrap each patty individually in saran wrap, and place in a freezer-safe bag. Make sure all air has been pushed out of the bag before sealing. Label the bag with the contents and date. Place in the freezer for 2-3 months. When ready to defrost, remove from the freezer. Transfer to the refrigerator to defrost overnight. Then heat in the oven at 350 F. for 10 minutes, flipping the vegan chickpea burgers halfway through at the 5-minute mark.
