Mix the marinade. In a bowl, whisk olive oil, minced garlic, lemon juice, honey, Dijon, smoked paprika, cumin, oregano, salt, and pepper.
Prep the chicken. Pat the chicken dry and slice into strips or bite-size pieces for quick cooking. Toss with the marinade.
Let sit 20–30 minutes at room temperature or up to 8 hours in the fridge.
Cook the grains. Rinse quinoa or rice. Cook according to package directions with a pinch of salt. Fluff and set aside.
Roast the veggies. Heat the oven to 425°F (220°C).
Toss bell pepper, onion, and broccoli with a drizzle of olive oil, salt, and pepper. Roast on a sheet pan for 15–18 minutes until tender with a little char. Add tomatoes for the last 5 minutes.
Sauté the greens. In a skillet over medium heat, add a splash of olive oil.
Wilt the spinach or kale with a pinch of salt for 1–2 minutes. Set aside.
Cook the chicken. Heat a large skillet over medium-high. Add a light coat of oil.
Cook marinated chicken in a single layer 3–4 minutes per side until golden and cooked through (165°F/74°C). Don’t crowd the pan; work in batches if needed.
Make the yogurt drizzle. Stir Greek yogurt, lemon juice, grated garlic, salt, and pepper. Thin with a little water until pourable.
Assemble the bowls. Spoon grains into bowls.
Top with roasted veggies, wilted greens, and chicken. Add avocado slices if using, sprinkle pepitas or almonds, and a handful of herbs.
Finish and serve. Squeeze fresh lemon over the top and drizzle with the yogurt sauce or a touch of olive oil. Taste and adjust salt as needed.
