Step 1

Place the salmon in a cutting board and cut crosswise into very thin, ¼-inch strips. Now, take a second pass at cutting, going over the pieces in the opposite direction so that you cut the strips into a dice. Continue cutting the salmon until the pieces are very small, about 1/8- to 1/4-inch each. (Be patient. Moist, tender patties will be your reward.)

Step 2

Transfer the salmon to a large mixing bowl. Add the herbs, Greek yogurt, lemon juice, salt, ginger, and black pepper. With a fork, mix to combine.

Step 3

Divide the mixture into 4 equal portions. With your hands, compact each portion into a patty that is about 1-inch thick. They might not hold together at first, but keep squeezing. Place the patties on a parchment-lined baking sheet or large plate. Refrigerate for at least 15 minutes or cover with plastic and refrigerate for up to 1 day.

Step 4

While the burgers chill, prepare the sauce: In a medium bowl, whisk together the Greek yogurt, vinegar, herbs, garlic powder, and salt. Refrigerate until you are ready to serve.

Step 5

Heat a nonstick skillet over medium-high heat. Add ½ tablespoon oil. Once the oil is hot and shimmering, gently lower the salmon patties onto it. Cook on the first side until crisp and golden brown, 4 to 5 minutes. Gently flip burgers and cook on the second side until crisp and the burgers register 145 degrees F on an instant read thermometer, about 4 minutes more.

Step 6

Serve the burgers immediately (on buns or inside of lettuce cups), topped with lots of the sauce and a sliced tomato if you like.
