01 - Combine rinsed quinoa, water, and 1/2 teaspoon salt in a medium saucepan. Bring to a boil over medium-high heat, then reduce to low, cover, and simmer for 15 minutes. Remove from heat and let sit for 5 minutes. Fluff grains with a fork.
02 - Rub chicken breasts with olive oil, smoked paprika, garlic powder, salt, and black pepper. Grill or pan-sear on medium heat for 6 to 7 minutes per side until fully cooked. Transfer to a cutting board, allow to rest for 5 minutes, then slice thinly across the grain.
03 - While the quinoa and chicken are cooking, halve cherry tomatoes, shred purple cabbage, julienne carrot, slice yellow bell pepper, wash spinach leaves, thaw or steam edamame, and slice cucumber as directed.
04 - In a small mixing bowl, whisk together extra-virgin olive oil, lemon juice, Dijon mustard, honey or maple syrup, salt, and black pepper until fully emulsified.
05 - Divide the cooked quinoa evenly among 4 meal-prep containers. Top each with sliced chicken breast, cherry tomatoes, purple cabbage, carrot, bell pepper, baby spinach, edamame, and cucumber, arranging each vegetable in a visually distinct layer.
06 - Drizzle each bowl with the prepared dressing, or pack dressing separately for freshness. Sprinkle with toasted pumpkin seeds and chopped parsley.
07 - Seal containers and refrigerate for up to 4 days. Add avocado or a wedge of lime just before serving if desired.
