Cook the quinoa. Rinse quinoa under cold water.
Add to a saucepan with chicken broth. Bring to a boil, then reduce to low, cover, and simmer for 15 minutes. Remove from heat and let steam, covered, for 5 minutes.
Fluff with a fork.
Season the chicken. Pat the chicken dry. Mix smoked paprika, garlic powder, cumin, oregano, salt, and pepper. Rub evenly over both sides of the chicken.
Cook the chicken. Heat 1 tablespoon olive oil in a skillet over medium heat.
Cook chicken 5–7 minutes per side, until golden and cooked through (internal temp 165°F/74°C). Rest for 5 minutes, then slice.
Prep the veggies. Halve tomatoes, dice cucumber, shred carrot, slice red onion, and slice avocado. Roughly chop the greens if needed.
Chop herbs.
Make the dressing. Whisk olive oil, lemon juice, Dijon, garlic, honey, red pepper flakes, salt, and pepper until emulsified. Taste and adjust acid, salt, or sweetness.
Assemble the bowls. Add a bed of quinoa and greens to each bowl. Top with sliced chicken, tomatoes, cucumber, carrot, and red onion.
Add avocado and feta. Sprinkle herbs.
Dress and serve. Drizzle with lemon-garlic dressing. Toss gently right before eating.
Add a squeeze of extra lemon if you like it brighter.
