Toss 2 cups of diced potatoes with 2 tbsp olive oil, salt, and pepper. Roast or air fry at 400F for 20 minutes until crispy.
In a skillet over medium-high heat, brown 1 lb of ground beef until fully cooked. Drain excess fat.
Sprinkle 1 cup of shredded cheddar cheese over the hot ground beef, cover with a lid, and let it melt for 2 minutes.
Whisk together 0.25 cup mayonnaise, 2 tbsp ketchup, and 1 tbsp yellow mustard to create the creamy dressing.
Assemble the dish by layering 4 cups chopped romaine lettuce, crispy potatoes, and cheesy ground beef.
Top with 1 cup cherry tomatoes, 0.5 cup sliced pickles, and a drizzle of the creamy dressing. Garnish with 1 tbsp sesame seeds.
