Prep the marinade: In a bowl, whisk lemon zest, lemon juice, minced garlic, olive oil, honey, oregano, smoked paprika, salt, and pepper.
Marinate the chicken: Slice chicken breasts horizontally for even cooking, or leave whole. Add to the marinade, toss to coat, and refrigerate 20–60 minutes.
Longer adds flavor, but don’t exceed 4 hours to avoid mushy texture.
Cook the grain: Prepare quinoa, brown rice, or farro according to package directions. Fluff with a fork and set aside.
Make the yogurt sauce: Stir together Greek yogurt, olive oil, lemon juice, grated garlic, herbs, salt, and pepper. Adjust lemon and salt to taste.
Chill until serving.
Chop the veggies: Dice cucumber, tomatoes, bell pepper, and onion. Roughly chop herbs. Keep greens washed and dried.
Cook the chicken: Heat a large skillet or grill pan over medium-high.
Add a light drizzle of oil. Cook chicken 4–6 minutes per side, depending on thickness, until the center is no longer pink and juices run clear. Aim for an internal temp of 165°F (74°C).
Let rest 5 minutes, then slice.
Deglaze for extra flavor (optional): Add a splash of water or chicken broth to the hot pan and scrape up browned bits. Drizzle over the chicken.
Assemble the bowls: Add a base of grains and greens. Top with sliced chicken, tomatoes, cucumber, bell pepper, onion, and herbs.
Add avocado and feta if using.
Finish with sauce: Spoon on the lemon garlic yogurt sauce. Add a squeeze of lemon and a crack of pepper.
Serve: Enjoy warm, or pack into containers for easy lunches.
