Preheat your oven to 400°F and dice the russet potato into small, uniform cubes.
Toss the potato cubes with half of the olive oil and a pinch of sea salt on a parchment-lined baking sheet.
Roast the potatoes for 20 minutes, flipping halfway through, until they are golden and crispy.
While the potatoes roast, heat the remaining olive oil in a skillet over medium-high heat and add the ground beef.
Cook the beef until browned and fully cooked through, seasoning it with garlic powder, sea salt, and black pepper.
In a small mixing bowl, whisk together the Greek yogurt, yellow mustard, smoked paprika, and apple cider vinegar to create the special sauce.
Finely shred the romaine lettuce and dice the white onion and dill pickles into small pieces.
Assemble the bowl by placing the shredded lettuce at the base, then topping with the seasoned beef and roasted potatoes.
Garnish with the diced onions and pickles, drizzle with the yogurt sauce, and finish with a sprinkle of sesame seeds.
