Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel and cube the sweet potato into half-inch pieces and place them on the prepared baking sheet.
Drizzle the sweet potatoes with half of the olive oil and season with the sea salt and black pepper.
Roast the sweet potatoes for 20 to 25 minutes until they are fork-tender and slightly caramelized on the edges.
While the potatoes roast, heat the remaining olive oil in a non-stick skillet over medium-high heat.
Add the ground turkey and garlic powder to the skillet, breaking the meat into small crumbles as it browns.
Cook the turkey until it is fully browned and no longer pink, then remove from the heat.
Slice the cucumber into half-moons, halve the cherry tomatoes, and slice the avocado into thin wedges.
Assemble the bowl by layering the roasted sweet potatoes and ground turkey, then topping with cucumber, tomatoes, avocado, cottage cheese, and pickled red onions.
