This did end up tasting just like a big mac but you do need to shuffle up the ingredients a bit. Firstly the current tsp of Worcestershire sauce is pointless, it won't add anything, I used 4 in the end. I also added 1 tsp onion powder and 1 tsp of garlic powder and finely diced onion when I was cooking the beef. I didn't bother with the hassle of a sauce and instead just drizzled ketchup and mustard over the top of the cheese before I added the other tortilla and then flipped it. Finally once it was flipped I added the pickles straight under what was now the tip tortilla. Basically tasted like a Big Mac which I'm quite happy with!
