In a shallow dish or pie plate, mix together ingredients for panko crust: panko bread crumbs, sea salt and ground black pepper.
Divide hearts of palm cake mix into eighths, form into patties. Patties will be loose.

Notes
Notes: Using dried onions is important in this recipe because they help soak up some of the moisture from the cakes. If you were to use fresh, they would add moisture, making them even more challenging to keep together.
