Mash the Beans: Mash the drained and rinsed cannellini beans in a large bowl until broken down into a suitable patty mixture.
Combine the Eggs: Add the eggs to the mashed beans and whisk until the eggs are evenly incorporated.
Season the Mixture: Whisk in the grated Parmesan cheese, onion powder, garlic powder, paprika, and kosher salt until well combined.
Add the Kale: Stir the steamed and chopped kale into the seasoned bean mixture until it is distributed throughout.
Add the Breadcrumbs: Stir in the panko breadcrumbs last, mixing until the ingredients form a cohesive mixture that can be shaped into patties.
Heat the Skillet: Heat the olive oil in a skillet over medium heat.
Shape the Patties: Shape the mixture into 6–8 patties, keeping the portions suitable for skillet cooking.
Cook the First Side: Working in batches, place 3–4 patties in the skillet and cook for 4–6 minutes, until the bottoms are golden brown.
Flip the Patties: Carefully turn each patty over and cook the second side for another 4–6 minutes, until golden brown.
Finish Cooking: Remove the cooked patties from the skillet and repeat the process with the remaining patties until the entire mixture has been cooked.
Serve or Freeze: Serve the patties immediately, or allow them to cool completely before wrapping them in plastic wrap and placing them in a freezer bag.
Freeze for Storage: Store the wrapped patties in the freezer for up to 1 month.
