Peel and chop the potato, then put on the stove to boil.
While it cooks, mash the canned salmon in a bowl with a fork. The soft bones can be mixed in for extra calcium, but feel free to remove them.
Add the chopped green onion, parsley, lemon zest, salt and pepper to the salmon. Mix well and set aside.
Once the potato is fully cooked, drain well and mash. Add this to the salmon mixture and mix well.
Then, add the eggs, stirring to fully combine. If the mixture feels too dry, add another.
Divide the mixture into equal balls, about 8 to 10, depending on the size you'd prefer. I like to use a cookie scoop to make this process easier. Press the balls into thick patties and set aside.
Heat your skillet over medium heat, adding oil when hot. Carefully place the patties in the pan. Let them cook for 4 minutes before flipping.
Cook on the other side for another 4 minutes, then remove the salmon cakes from the pan. Cool for a few minutes before eating.
