Preheat your oven to 400°F and line a baking sheet with parchment paper.
Peel and dice the sweet potato into half-inch cubes, then toss with half of the olive oil, sea salt, and black pepper.
Spread the sweet potatoes on the baking sheet and roast for 20-25 minutes until the edges are golden and tender.
While the potatoes roast, heat the remaining olive oil in a large skillet over medium-high heat.
Add the ground beef to the skillet, breaking it up with a spatula, and cook until browned and cooked through.
Season the beef with garlic powder and coconut aminos, stirring well to coat the meat as it finishes browning.
Dice the cucumber, red bell pepper, and red onion into small, uniform pieces.
Assemble the bowl by placing the roasted sweet potatoes and savory beef on one side, and the fresh cucumber, pepper, and onion on the other side.
