Heat 1 tsp of olive oil in a non-stick frying pan. When heated add red pepper, garlic, and onion. Sautée for 3-5 mins until softened. Remove from heat and allow to cool.
Combine cooled red pepper, garlic, and onion mix with celery, mayonnaise, parsley, panko crumbs, egg, and salmon. Mix until combined.
Once mixed form 8 salmon balls using an ice cream scoop.
Heat the same non-stick pan. Add 1 tbsp of olive oil. Once heated, add salmon balls to the pan (be sure not to overcrowd the pan), and flatten it with a spatula into the shape of a patty.
Cook for 2-3 mins per side or until golden brown. Repeat for remaining salmon cakes. Let cool and enjoy!
