About the Ingredients

1 cup (200g) quinoa, rinsed

Protein-packed grain alternative to rice. Substitute with couscous or farro for a different texture.

2 cups (480ml) low-sodium vegetable broth

Adds flavor to quinoa. Use water + a pinch of salt if you prefer.

1 lb (450g) boneless, skinless chicken breasts

Lean protein. Swap with tofu or chickpeas for a vegetarian version.

2 tbsp (30ml) olive oil, divided

Use extra-virgin for best flavor. Avocado oil also works for high-heat roasting.

1 lemon, zested and juiced

Fresh lemon brightens the dish. Bottled juice works in a pinch, but zest adds more punch.

2 cloves garlic, minced

Aromatics. Use 1/2 tsp garlic powder if you're out of fresh.

1 tsp dried oregano

Classic herb for chicken. Try thyme or basil for a different vibe.

1 red bell pepper, sliced

Adds sweetness and crunch. Any color bell pepper works.

1 yellow squash, sliced

Mild and tender. Zucchini is a perfect substitute.

1 cup (150g) cherry tomatoes

Bursts of juiciness. Grape tomatoes are equally good.

1/4 cup (60g) tahini

Sesame paste for the dressing. Use Greek yogurt mixed with lemon if you're nut-free.

2 tbsp (30ml) water

Thins the tahini dressing. Add more if needed to reach drizzling consistency.

Tips & Tricks

Don't overcook the chicken

Use a meat thermometer to ensure it reaches 165°F (74°C). Overcooked chicken becomes dry and tough.

Roast veggies in a single layer

Crowding the pan causes steaming instead of roasting, leading to soggy veggies. Use two pans if needed.

Let the quinoa rest

After cooking, let it sit for 5 minutes before fluffing. This makes it light and fluffy, not mushy.

Step-by-Step Instructions

1. Preheat Oven

Preheat your oven to 425°F (220°C). This high heat will caramelize the veggies, bringing out their natural sweetness.

2. Cook Quinoa

In a medium saucepan, combine quinoa and vegetable broth. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let stand 5 minutes, then fluff with a fork.

3. Season Chicken

While quinoa cooks, whisk together 1 tbsp olive oil, lemon zest, lemon juice, garlic, oregano, and a pinch of salt and pepper. Coat chicken breasts with this mixture.

4. Roast Veggies

On a baking sheet, toss bell pepper, squash, and cherry tomatoes with remaining 1 tbsp olive oil, salt, and pepper. Spread in a single layer and roast for 20-25 minutes, until tender and edges are slightly charred.

5. Cook Chicken

Heat a grill pan or skillet over medium-high heat. Cook chicken for 6-7 minutes per side, until golden brown and internal temperature reaches 165°F (74°C). Let rest 5 minutes before slicing.

6. Make Dressing

In a small bowl, whisk tahini, water, and a pinch of salt until smooth. Add more water if needed to achieve a drizzle consistency.

7. Assemble Boxes

Divide quinoa among 4-5 lunch containers. Top with roasted veggies and sliced chicken. Drizzle with tahini dressing just before serving, or pack it separately.

Delicious Variations

Mediterranean

Swap chicken for falafel, add cucumber, olives, and feta cheese.

Asian-Inspired

Use brown rice instead of quinoa, add edamame and a soy-ginger dressing.

Southwest

Replace chicken with black beans, add corn, avocado, and a lime-cilantro vinaigrette.
