Begin by bringing a large pot of salted water to a rolling boil over high heat. Once boiling, add your pasta and cook according to package instructions until al dente, usually about 10-12 minutes. Reserve ½ cup of pasta water before draining the pasta in a colander, and set aside while you prepare the rest of the dish.

In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. While the oil heats, season your chicken breast with salt, pepper, dried oregano, and thyme. Once the oil shimmers, add the seasoned chicken to the skillet and cook for 6-8 minutes, turning occasionally until it's golden brown and cooked through. Remove the chicken from the skillet and let it rest on a cutting board.

In the same skillet, add an additional tablespoon of olive oil if needed, then toss in the chopped onion and diced red bell pepper. Sauté these colorful veggies over medium heat for about 3-4 minutes until they soften. Next, add minced garlic to the skillet and cook for another minute, stirring constantly until fragrant and golden, ensuring not to burn the garlic.

Stir in the sun-dried tomatoes, halved cherry tomatoes, and Kalamata olives into the skillet, allowing everything to combine well. Cook for about 2 minutes until the mixture is heated through and the tomatoes start to break down slightly. This step creates a rich, flavorful foundation for your Chicken Feta Greek Pasta.

Return the cooked chicken to the skillet and add a handful of baby spinach. Toss everything together on medium heat until the spinach wilts down, which should take about 1-2 minutes.

Once the spinach has wilted, add the drained pasta to the skillet along with the reserved pasta water. Toss everything together vigorously to combine until the pasta is thoroughly mixed with the chicken and vegetables.

Finally, remove the skillet from heat. Gently fold in the crumbled feta cheese and chopped fresh parsley, allowing the cheese to slightly melt into the warm pasta. Taste and adjust seasoning to your preference. Serve your delightful Chicken Feta Greek Pasta immediately, garnished with additional parsley for a fresh touch!
