Cook the pasta according to package instructions. Drain and set aside.
Prepare the chicken: Cut the chicken into bite-sized pieces and toss with olive oil, garlic powder, smoked paprika, black pepper, salt, and optional chili flakes.
Heat a skillet over medium-high heat and cook the chicken for 4–5 minutes per side, until golden brown and fully cooked. Let rest for a few minutes.
Prepare the vegetables: Sauté in 1 teaspoon olive oil for 3–5 minutes until tender, or roast in the oven at 400°F for 15–20 minutes.
Assemble the bowl: Place pasta in a bowl, top with chicken, vegetables, and feta or avocado.
Add fresh herbs and a squeeze of lemon juice. Drizzle with extra olive oil if desired.
Serve warm and enjoy a nutrient-rich, protein-packed meal.
