Prep the chicken: Pat chicken dry. In a bowl, mix olive oil, salt, pepper, garlic powder, onion powder, Italian seasoning, and smoked paprika if using.
Rub evenly over the chicken.
Cook the chicken: Grill over medium-high heat 5–7 minutes per side, bake at 425°F (220°C) for 18–22 minutes, or pan-sear 6–7 minutes per side until the thickest part reaches 165°F (74°C). Rest 5–10 minutes, then slice or cube.
Make the dressing: In a bowl, whisk Greek yogurt, mayo, Parmesan, anchovy, garlic, lemon juice, Dijon, Worcestershire, and pepper. Add water a little at a time until creamy and pourable.
Taste and add salt and more lemon if needed.
Prep the veggies: Wash and dry romaine thoroughly (excess water wilts greens). Chop into bite-size pieces. Dice cucumber and halve tomatoes.
Cook the grain (optional): If adding farro, quinoa, or rice, cook according to package directions and let cool fully before packing.
Assemble for meal prep: Use 4–5 containers.
If including grains, add them to one side. Layer romaine on the other side, then cucumbers and tomatoes. Top with sliced chicken and a sprinkle of Parmesan.
Pack the dressing separately: Divide into small leakproof containers (2–3 tbsp per serving).
Keep croutons or roasted chickpeas in a separate bag so they stay crunchy.
Store: Seal everything and refrigerate. Add lemon wedges to each container if you like a bright finish.
Serve: Right before eating, drizzle dressing over the salad, toss, and finish with a squeeze of lemon and extra Parmesan. Add croutons or chickpeas last.
