Preparation

• Stir together first 6 ingredients in a large bowl. Divide mixture into 8 balls.
  
  Flatten each ball into a 3-inch patty. Divide smoked salmon into 4 pieces, and place in center of 4 patties. Place remaining patties over salmon, pressing edges to seal; coat cakes in breadcrumbs.
  
  Heat oil in a large nonstick skillet over medium-high heat; add cakes, and cook, in batches, 3 to 4 minutes on each side or until golden. Drain on paper towels. Serve immediately with Spicy Avocado Tartar Sauce. Garnish with fresh cilantro sprigs, if desired.
