Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the cubed sweet potatoes with half of the olive oil and a pinch of salt, then roast for 20-25 minutes until tender and slightly browned.
Season the chicken breast with salt, pepper, and garlic powder, then grill over medium-high heat for 6-7 minutes per side until fully cooked.
While the chicken and potatoes cook, place the raw kale in a bowl with the lemon juice and a tiny pinch of salt, massaging with your hands for 1-2 minutes until softened.
Prepare the quinoa according to package directions if not already cooked, ensuring it is light and fluffy.
Slice the grilled chicken into thin strips and pit/slice the avocado.
Assemble the bowl by placing the quinoa and massaged kale at the base, then topping with the roasted sweet potatoes, grilled chicken, and fresh avocado slices.
