Pre-heat oven to 375 degrees. Line a baking sheet with aluminum foil and spray with non-stick cooking spray.
Arrange cod filets in single layer on lined baking sheet. Season with Oh My Spice! seasoning and bake for 10-12 minutes or until fish is cooked through and flakes easily with a fork.
Add butternut squash to a large pot. Cover with water and bring to a boil for 10-15 minutes or until squash is tender. Drain water and add remaining squash mash ingredients. Mash until it reaches desired consistency.
Heat olive oil over medium-high heat in a large skillet. Add kale and toss with Dijon mustard until kale is bright green and has softened to desired texture.
Divide butternut squash mash, cod, and sautéed kale evenly among 4 serving containers.
