1-First step: cook the quinoa Start by rinsing the quinoa under cold water. This matters because quinoa has a natural coating called saponins, and rinsing helps remove that bitter taste. Place 1 1/2 cups uncooked quinoa in a pot with 2 cups chicken broth and 3/4 cup water. Cook it following the package directions until the grains are tender and the liquid is absorbed. Once the quinoa is done, turn it into a large bowl and fluff it with a fork. Then let it cool completely. This part is important because warm quinoa can wilt the vegetables and soften the feta too much. If you are making the salad for meal prep, cool the quinoa before storing it so the texture stays nice.

2-Second step: sauté the spinach Heat a medium nonstick skillet and spray it lightly with olive oil cooking spray. Add the 2 cups chopped baby spinach, or use tender kale without stems if that is what you have on hand. Cook the greens just until wilted, which usually takes only a minute or two. Transfer the spinach to a plate and let it cool. The goal here is not to cook it down until it loses all texture. You want it soft enough to blend into the quinoa, but still bright and fresh. This keeps the Mediterranean chicken quinoa salad from feeling too heavy or soggy.

3-Third step: prep the vegetables and protein While the quinoa and spinach cool, chop the remaining ingredients into small, even pieces. Dice the red onion, green bell pepper, red bell pepper, cucumber, and seeded Roma tomatoes. Chop the parsley, and make sure the chicken breast is already cooked and cooled before you add it to the bowl. Small, even pieces help each bite stay balanced. If you are starting with raw chicken, bake seasoned breasts or cutlets at 350°F until the internal temperature reaches 165°F. Let them cool before chopping so the juices stay inside. This makes the chicken tender and perfect for a Mediterranean chicken quinoa salad that can be served cold or at room temperature.

4-Fourth step: combine the salad base In a large mixing bowl, combine the cooled quinoa and the sautéed spinach. Add the chopped chicken, red onion, green bell pepper, red bell pepper, cucumber, tomatoes, parsley, kalamata olives, and feta cheese. Toss gently so everything gets mixed without crushing the softer ingredients. This is the point where the salad starts looking like a real meal instead of separate parts. The colors are bright, the textures are mixed, and the bowl already smells fresh. If you are making the salad for lunch later, you can stop here and store the base ingredients separately from the dressing.

5-Fifth step: whisk the dressing In a small bowl or jar, whisk together 4 tablespoons fresh lemon juice, 6 tablespoons balsamic vinegar, 1/4 cup extra virgin olive oil, 1 teaspoon salt, and 1/2 teaspoon pepper. Whisk until the dressing looks blended and glossy. A jar with a lid is handy here because you can shake it instead of whisking. Use high-quality balsamic vinegar and extra virgin olive oil if you can. The dressing is simple, so the flavor of each ingredient really comes through. A good dressing can take this Mediterranean chicken quinoa salad from fine to really memorable.

6-Final step: dress and serve Pour the dressing over the salad and toss gently to combine. You want each ingredient lightly coated, not drowned. Taste and adjust if needed, though the measured dressing usually gives a nice balance of tang, salt, and richness. Serve the salad right away if you want the freshest texture. It also holds well in the fridge for a short time, so it works for packed lunches or next-day dinners. If you like a lower-calorie meal, keep the dressing on the side and drizzle it over each portion as you serve.
