In a large skillet, heat the olive oil over medium-high heat. Add the ground beef and cook until browned and cooked through. Season it with salt, pepper, garlic powder, and onion powder. Allow it to cool a bit after cooking.

In a large salad bowl, combine the chopped romaine lettuce, cooled ground beef, shredded cheddar cheese, sliced pickles, diced onions, and cherry tomatoes. Toss everything together to blend well.

In a separate bowl, mix together mayonnaise, ketchup, yellow mustard, white vinegar, and salt. Whisk these ingredients until they are fully combined and smooth.

Pour the prepared dressing over the salad. Toss it again to ensure everything is evenly coated with the dressing.

Serve the salad immediately for the best crunch and freshness. Dig in and enjoy your homemade Big Mac flavor!
