  • 1 cup (250 mL) mayonnaise
  • 1 tbsp (15 mL) capers, chopped
  • 1 tsp (5 mL) fresh lemon juice
  • 1 dill pickle, finely chopped
  • 1 small Ontario Shallot, diced
  • 1 green onion, chopped
  • Pinch cayenne pepper
  • Salt and freshly ground black pepper 


  • 1-1/2 lbs (750 g) fresh Ontario Walleye Fillets, skin and bones removed
  • 1 Ontario Egg White
  • 1 tbsp (15 mL) potato starch
  • 1 cup (250 mL) diced (1/4-inch/0.5 cm) Ontario Mozzarella Cheese
  • 1/4 cup (50 mL) finely diced Ontario Red Onion
  • 2 tsp (10 mL) chopped fresh Ontario Dill
  • 2 green onions, minced
  • 1 lemon, zested and juiced
  • Salt and freshly ground black pepper 
  • 1/4 cup (50 mL) vegetable oil
  • 6 burger buns, lightly toasted
  • 6 Ontario Boston Greenhouse Lettuce Leaves
  • 1-1/2 cups (375 mL) creamy coleslaw 
  • Salt and vinegar potato chips


Tartar Sauce: In medium bowl, stir together mayonnaise, capers, lemon juice, dill pickle, shallot and green onion. Season with cayenne pepper and salt and pepper to taste. Cover and refrigerate until needed. 
Burgers: Rinse fillets under cold water and pat dry with paper towel. Divide fish evenly. Place one half into food processor; add egg white and sprinkle with potato starch. Pulse until smooth; about 1 minute. Transfer to mixing bowl and refrigerate. 

Dice remaining fillets into 1/4 to 1/2-inch (0.5 to 1-cm) cubes. Stir into refrigerated mixture along with the cheese, red onion, dill and green onions. Stir in 1/2 tsp (2 mL) of lemon zest and 1 tsp (5 mL) of lemon juice. Season with salt and black pepper; mix well. Cover and refrigerate for 30 minutes.
Scoop 6 equal sized balls. In large skillet, heat 2 tbsp (25 mL) of the oil over medium-high heat. Place 3 fish balls in skillet and press with spatula to flatten about 1-inch (2.5 cm) thick. Cook for 4 to 5 minutes per side until burgers are fully cooked. Repeat with remaining oil and burgers. 

Serve immediately on buns with lettuce leaves, coleslaw, tartar sauce and potato chips.
