Marinate the chicken: In a bowl, whisk olive oil, lemon zest and juice, garlic, oregano, cumin, salt, pepper, and paprika if using. Add chicken and toss to coat.
Marinate at least 20 minutes, up to 8 hours in the fridge.
Cook your base: Prepare quinoa, brown rice, or farro according to package directions. Fluff and let cool slightly so it doesn’t wilt your veggies.
Make the yogurt sauce: Stir together Greek yogurt, lemon juice, grated garlic, olive oil, herbs, salt, and pepper. Adjust lemon or salt to taste.
Chill until serving.
Sear or bake the chicken: Stovetop: Heat a large skillet over medium-high. Add a light drizzle of oil. Cook chicken 5–7 minutes per side until browned and cooked through (internal temp 165°F/74°C).
Rest 5 minutes.
Oven: Roast at 425°F (220°C) for 18–22 minutes, depending on thickness. Broil 1–2 minutes for color if desired. Rest 5 minutes.
Chop and assemble veggies: Halve tomatoes, dice cucumber, slice onion, rinse chickpeas, and chop herbs.
Keep components separate if meal-prepping.
Slice the chicken: Cut across the grain into strips or cubes for easy bowl assembly.
Build the bowls: Add a scoop of grains or greens, then top with chicken, tomatoes, cucumber, red onion, chickpeas, olives, and feta. Spoon on yogurt sauce and finish with fresh herbs. Add a squeeze of lemon if you like it extra bright.
Season to finish: A quick pinch of salt, pepper, and a drizzle of olive oil pulls everything together.
