In a medium bowl, combine all the ingredients for the salmon mixture. Do not overmix.
Form the mixture into twelve 2 1/2-inch cakes by 1 1/2-inch thick. Coat both sides with the Panko bread crumbs, shaking off any excess crumbs. Don't coat too heavy; the cakes should be light.
Heat the olive oil over medium-high heat in a large, non-stick skillet. Cook 6 at a time, about 3 minutes per side, turning once, until golden brown. Remove from the oil and place on a paper towel to drain. Cook the remaining cakes until done.
Serve immediately with the Cucumber Corn Salsa.
