Ingredients and directions below
500g extra lean mince
1 large onion (diced)
4 tbsp extra light mayonnaise
4 tbsp tomato ketchup
8 Gherkins (sliced)
Iceberg Lettuce (chopped)
8 slices Dairylea light slices
Salt and Pepper
Put the mince and onion in a pan and fry (medium heat) until the mince is brown and the onions are soft, season to taste.
Mix the ketchup and mayonnaise to make a burger/thousand island sauce.
Layer up the dish with shredded lettuce and minced beef mixture. Drizzle on some of the burger sauce and sprinkle on the gherkins and top with cheese.
If you use ketchup with the extra light mayonnaise and Dairylea as a healthy extra it's only 2 syns per portion
