Start by finely dicing the shallots and chopping the kale. Cook the quinoa according to package instructions if you haven’t done so already. Make sure the quinoa is cooled before mixing it into the burger mixture.
In a large skillet, heat 1 teaspoon of olive oil over medium heat. Add the diced shallots and sauté for about 2-3 minutes until they become translucent. Add the chopped kale and cook for an additional 2-3 minutes until wilted. Remove from heat and let cool slightly.
In a large mixing bowl, add the wild salmon fillet. Using a fork, break the salmon into small pieces. This will ensure that the salmon is evenly distributed throughout the burgers.
Add the sautéed shallots and kale to the bowl with the salmon. Then, add the cooked quinoa, Dijon mustard, Old Bay seasoning, and beaten egg. Season with kosher salt and freshly ground black pepper. Mix everything well until fully combined.
Using your hands, form the mixture into patties, about 3-4 inches in diameter. You should be able to make around 6-8 patties, depending on the size. Place the patties on a plate and refrigerate for at least 30 minutes to help them hold together during cooking.
In the same skillet, heat the remaining 2 1/2 tablespoons of olive oil over medium heat. Carefully add the salmon patties to the skillet. Cook for about 4-5 minutes on each side, or until they are golden brown and cooked through. Be gentle when flipping to prevent the patties from breaking apart.
While the burgers are cooking, prepare the salad by combining the baby arugula and diced pink grapefruit in a large bowl. In a small bowl, whisk together the champagne vinegar, minced shallots, 1 1/4 teaspoons of Dijon mustard, and a pinch of salt and pepper to create the dressing. Drizzle the dressing over the salad and toss gently to combine.
Serve the Healthy Salmon Quinoa Burgers warm, topped with the arugula grapefruit salad on the side. These burgers are perfect for a light lunch or a satisfying dinner.
