Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel and dice the sweet potato into uniform 1/2-inch cubes to ensure even cooking.
Toss the sweet potato cubes with olive oil, sea salt, and black pepper on the baking sheet, then roast for 20-25 minutes until tender and slightly caramelized.
While the potatoes roast, heat a large non-stick skillet over medium-high heat and add the ground beef, breaking it into small crumbles with a wooden spoon.
Cook the beef until fully browned, then stir in the minced garlic, grated fresh ginger, and gochugaru for an aromatic base.
Pour in the coconut aminos and toasted sesame oil, stirring constantly for 2 minutes to allow the flavors to meld and glaze the beef.
Add the fresh spinach to the skillet and sauté for 1 minute until the leaves are just wilted but still bright green.
Divide the roasted sweet potatoes into bowls, top with the savory beef and spinach mixture, and finish with a side of kimchi and a sprinkle of sesame seeds.
