Step 1: Prepare the Chicken: In a bowl, toss the chicken cubes with 1 tablespoon of olive oil, salt, pepper, and red pepper flakes (if using). Ensure the chicken is evenly coated for a balanced flavor profile.
Step 2: Saut the Vegetables: Heat the remaining 1 tablespoon of olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add the diced red onion and cook until softened, about 5 minutes. Add the minced garlic and cook for another minute until fragrant, being careful not to burn.
Step 3: Add the Remaining Vegetables: Stir in the diced bell peppers and zucchini. Cook for about 5-7 minutes, until the vegetables are slightly tender. This step helps to release their natural sweetness and flavors.
Step 4: Incorporate the Chicken: Add the seasoned chicken cubes to the skillet and cook until browned on all sides, about 5 minutes. This step sears the chicken, sealing in the juices and adding a rich, savory note.
Step 5: Add Quinoa, Broth, and Seasonings: Pour in the rinsed quinoa and chicken broth. Stir in the dried oregano, dried basil, sun-dried tomatoes, and Kalamata olives. Season with salt and pepper to taste. The broth will cook the quinoa and infuse all the ingredients with flavor.
Step 6: Bake in the Oven: Bring the mixture to a simmer, then cover the skillet or Dutch oven and transfer it to a preheated oven at 375F (190C). Bake for 25-30 minutes, or until the quinoa is cooked through and the liquid is absorbed. Baking the dish allows the flavors to meld together, creating a harmonious blend of tastes.
Step 7: Finish with Lemon and Garnish: Remove the skillet from the oven and stir in the lemon juice. Garnish with fresh parsley and crumbled feta cheese (if using). The lemon juice adds brightness and acidity, while the parsley provides a fresh, herbaceous note.
Step 8: Portion and Store: Allow the dish to cool slightly before portioning it into meal prep containers. This allows the flavors to further meld and prevents condensation from forming during storage. Store in the refrigerator for up to 4 days.
Optional tips: For a vegetarian option, replace the chicken with an equal amount of chickpeas. For added heat, include a pinch of red pepper flakes. Feel free to substitute the vegetables with your favorite seasonal alternatives.
