Add potatoes to salted boiling water. Simmer for 10 minutes (leave skin on for extra roughage). Add peas and bring back to boil for 2 minutes. Drain.
Add salmon to a mixing bowl and break up with a fork.
Add zest, flour, mustard and egg to the bowl and mix to combine.
Roughly mash potatoes and peas. Stir thoroughly through the salmon mixture.
Pour extra flour onto a plate. Divide the salmon mixture into 10 portions and form into patties approx 2cm thick. Turn on the floured plate to lightly dust each pattie.
Bring frypan to medium heat, add olive oil. Lightly fry each pattie for 3-4 minutes each side.
Create a "cheat's" aoili. Stir minced garlic through mayonaise.
Serve 2 patties with a dollop of aoili and green salad.
Notes
Salmon can be replaced with tuna. Obviously they would no longer be salmon cakes lol
