Prepare Salmon and Remove Bones and Skin: Open the can of red salmon and drain the liquid. Carefully remove the salmon from the can and place it in a bowl. Gently inspect the salmon for bones. Using your fingers or a fork, carefully flake the salmon, feeling for and removing any small bones you encounter. If there is skin attached, peel it away and discard.
Add Grated Veggies and Seasonings: Add the grated potato, carrot, and zucchini, followed by the red onion, dill, lemon juice and lemon zest. Mix together with a spoon, and season with salt and pepper.
Add Egg and Breadcrumbs: Add the egg and mix though, followed by breadcrumbs, mixing through until combined
Shape into Patties: Form the salmon mixture into 6 patties, usually about 2-3 inches in diameter. Set aside on a separate plate as you make them.
Cook Fritters: Place the patties in the hot oil and cook for 3-4 minutes on each side or until they are golden brown and cooked through. Once cooked, transfer the fritters to a paper towel-lined plate to absorb any excess oil.
Serve: Serve the salmon fritters warm, with lemon wedges for squeezing over the top, a dill sauce, or homemade tartare sauce.
