Cook the quinoa. Place 3 cups of water to boil over high heat on the stovetop. Add the quinoa and a pinch of salt to the water. Bring up to a boil and then down to a simmer, covering the pot with its lid.
While the quinoa cooks, prepare the remaining ingredients. First, mince or grate the garlic.
Then, in a small bowl or jar with a lid, add the lemon juice, olive oil, garlic, salt and pepper to taste, and cumin or coriander. Whisk or shake until well-combined.
Finely dice the cucumber.
Slice the cherry tomatoes into halves.
Then, cook the salmon. Pat salmon dry using paper towels. Season with salt on both sides.
Place a pan over medium heat. Once hot, add olive oil. Then place salmon in the pan skin side down and cook for 4 minutes per side, depending on the thickness of the fish. It should reach an internal temperature of 125-130 degrees Fahrenheit and flake easily. This will result in medium-rare fish.
Let the salmon rest for a few minutes, remove the skin, then flake the salmon.
Once the quinoa has finished cooking, it will have a white ring around each of the individual grains, around 15 to 20 minutes. If there is any water remaining in the pan, you can strain the quinoa using a fine mesh sieve and place it back in the pan or on a flat surface, like a plate or a baking sheet, to cool quicker.
After the quinoa has cooled, combine cooked quinoa, salmon, remaining salad ingredients, and lemon salad dressing in a large bowl and stir to combine.
Taste for seasoning and serve!
