• Prepare the Beef: In a large skillet, cook the ground beef over medium-high heat until browned. Season with salt, pepper, garlic powder, and onion powder. Drain excess fat.
• Make the Special Sauce: In a bowl, mix together mayonnaise, ketchup, sweet pickle relish, vinegar, sugar, and onion powder until well combined.
• Assemble the Tacos: Heat taco shells according to package instructions. Spread a generous amount of special sauce inside each shell.
• Add the Beef: Spoon the seasoned ground beef into each taco shell.
• Top It Off: Add shredded lettuce, diced onions, pickle slices, and shredded cheddar cheese on top of the beef.
• Serve Immediately: Enjoy your Big Mac Smash Tacos while they’re hot and crispy.

Notes

• For an extra kick, add a few dashes of hot sauce to the special sauce.
• You can substitute ground turkey for a leaner option.
