Place salmon in food processor, cover, and pulse about 5-7 times to coarsely grind. (Do not over-process and turn into paste.) Set aside.
In a large bowl, combine panko, green onions, cilantro, ginger, garlic, eggs, soy sauce, lemon juice, and salt. Add salmon and stir to combine well.
Line a sheet tray with parchment, wax paper, or nonstick foil. Using a 2/3 C measuring cup, scoop out salmon mixture and form into 1-inch thick patties. Place on tray. Makes 6 patties. Cover with plastic wrap and place in refrigerator for 30 minutes to 6 hours.
While salmon is firming in the fridge, make the Sriracha Lime Mayo by adding mayo, sriracha, lime juice, red onion, and salt to a small bowl. Stir to combine. Taste and add more sriracha if needed. Cover and place in fridge until ready to serve.
Heat a large nonstick skillet to medium high. Add olive oil. Place salmon burgers in skillet and cook for 4-5 minutes per side or until cooked through and internal temperature reaches 160 degrees F.
Serve with Sriracha Lime Mayo on buns with lettuce and avocado (suggested).
