Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Scrub the russet potato and dice it into half-inch cubes, then toss them in a bowl with the olive oil, garlic powder, and half of the sea salt.
Spread the potatoes in a single layer on the baking sheet and roast for 25 to 30 minutes, flipping once, until they are golden brown and crispy.
While the potatoes roast, heat a skillet over medium-high heat and add the ground beef, breaking it into small crumbles with a spatula.
Cook the beef until browned and cooked through, then season with the remaining sea salt and the black pepper.
Prepare the bowl base by chopping the romaine lettuce and halving the cherry tomatoes, then thinly slice the red onion and dill pickles.
Assemble the bowl by placing the lettuce at the bottom, followed by the crispy roasted potatoes and the sautéed ground beef.
Top the bowl with the tomatoes, red onion, and pickles for a fresh and tangy finish before serving.
