Heat oven to 400 F. Add quinoa and water to a rice cooker or pot on the stove and cook until all liquid has absorbed. Once cooked, let cool while you prep the rest of the ingredients.
Add squash to a large baking sheet then line with parchment paper. Drizzle with a bit of olive oil, about 1/2 tbsp, then season with salt & pepper. Roast for 15 minutes.
Meanwhile, season chicken with cajun seasoning and a bit of salt & pepper. Heat 1 tbsp olive oil in a large skillet over medium-high heat then cook chicken for 5 minutes per side. Remove from heat, let rest then slice into bite-sized pieces.
While quinoa, squash and chicken cook, make the cider vinaigrette by mixing all ingredients together, then chop the kale.
Add kale to a large bowl and massage with remaining 1/2 tbsp olive oil.
Meanwhile, heat the same skillet the chicken was cooked in over medium heat, then toast pumpkin seeds and pecans for 1 minute. Add in maple syrup and toast another minute until crispy then remove from heat.
Now you're ready to build your salad! Add quinoa, chicken, sliced apples, cooked squash, pomegranates, feta and nut brittle, then toss with dressing. Serve and enjoy!
