In a large skillet, heat over medium-high heat and add ground beef. Cook for 5-6 minutes, breaking it apart until browned. Drain grease, season with salt, garlic powder, Worcestershire sauce, and black pepper. Remove from heat.

Finely chop half a red onion. In a separate pan, heat oil and sauté onions for 3-4 minutes until translucent. Alternatively, add to the beef in the last minute of cooking.

Prepare frozen French fries according to package instructions (about 20 minutes at 425°F).

In a medium bowl, mix together mayonnaise, sweet pickle relish, Dijon mustard, paprika, and white vinegar. Add garlic and onion powder, stir well, and refrigerate for at least 10 minutes.

Divide shredded romaine lettuce among four bowls. Top with seasoned beef, grape tomatoes, shredded cheese, pickle slices, and crispy French fries. Drizzle with special sauce before serving.
