These salmon cakes are a great way to use up leftover salmon. The salmon is mixed with breadcrumbs, egg, and spices, then formed into patties and pan-fried until crispy. The avocado salsa is made with diced avocado, tomato, red onion, and lime juice, and adds a fresh and flavorful topping to the salmon cakes. Serve with a side salad for a light and healthy meal.
