In a small mixing bowl, whisk together the Greek yogurt, yellow mustard, smoked paprika, and apple cider vinegar until smooth to create the zesty sauce.
Heat the olive oil in a large cast-iron skillet or non-stick pan over medium-high heat.
Add the ground beef to the pan, seasoning it evenly with sea salt, black pepper, and garlic powder.
Press the beef down firmly and let it sear undisturbed for 3-4 minutes until a deep golden-brown crust forms.
Break the beef into large, chunky crumbles and continue cooking for another 2 minutes until fully cooked through.
While the beef crisps, chop the romaine lettuce, halve the cherry tomatoes, finely dice the red onion, and slice the dill pickles.
Assemble the bowl by placing the lettuce at the base, followed by the tomatoes, onion, and pickles.
Top the vegetables with the hot, crispy beef and drizzle the zesty yogurt sauce over the entire bowl before serving.
