Combine the balsamic vinegar, maple syrup, garlic, soy sauce and olive oil in a medium container.
Butterfly each chicken breast and place in the container with the marinade. Cover and refrigerate for at least two hours or overnight.
Preheat oven to 400°F. Line a baking sheet with aluminum foil. Set aside.
In a large bowl combine the acorn squash, carrots, red onion, garlic, olive oil, garlic powder, rosemary, thyme, and salt. Toss until all the vegetables are coated in oil and seasoning.
Spread the vegetables evenly on the prepared baking sheet. Roast the vegetables for 15-20 minutes or until they are tender.
In a small bowl, combine all the ingredients for the dressing. Mix well and set aside.
Cook the pasta according to the package instructions. Reserve 1⁄4 cup pasta water. Set the cooked pasta aside.
Heat a large skillet on medium-high heat. Add in the chicken. Cook on one side for 3-4 minutes. Flip and continue to cook until the chicken is firm and the juices run clear, about another 3-4 minutes. Place the fully cooked chicken onto a cutting board and allow it the rest for a few minutes before slicing.
Heat a large pan over medium heat. Add in all the roasted vegetables, the cooked pasta, the chopped kale, the 1⁄4 cup reserved pasta water and the dressing. Toss to combine. Cooked until the kale is wilted, season with salt and pepper.
Divide the pasta salad among four bowls, top with the sliced chicken breast. Garnish with pumpkin seeds and crumbled feta. Enjoy!
