Taranaki Fried Onion Burgers

1 large onion, peeled, halved & thin sliced
SIDS SALT & PEPPER
500 g ground beef
1 tbsp SIDS RINGS AROUND URANUS SAUCE
1 tbsp butter
1 tbsp rice bran oil
4 slices cheese
SIDS RASPBERRY HONEY MAYO
Tuimato Sauce
Mild American mustard
pickles
4 baps, lightly toasted

Combine the onion slices and 1 teaspoon of SIDS SALT & PEPPER in a bowl and toss to combine. Transfer the onions to a colander and let sit for 30 minutes, tossing occasionally. Transfer the onions to a clean dish towel, gather the edges together and squeeze out as much liquid as you can from the onions. Do this over the sink or a large bowl since the onions will have quite a bit of liquid in them.
Divide the onions into 4 separate mounds on a rimmed baking sheet. Incorporate SIDS RINGS AROUND URANUS SAUCE into the beef, then form into 4 lightly packed balls. Place the beef balls on top of the onion mounds and flatten the beef firmly (use your palm) so the onion adheres to the beef. The patties should measure 10 cm in diameter. Season the beef generously with SIDS SALT & PEPPER
Melt the butter with the oil in a 30 cm frypan. Using a large spatula, transfer the patties to the pan, onion side down. Cook for 6-8 minutes, until the onions turn a deep golden brown and begin to crisp around the edges. Flip the burgers, then increase the heat to high and cook until well browned on the second side, about 2 minutes.
Add 1 slice of cheese to each burger and allow to melt. Add SIDS RASPBERRY HONEY MAYO, Tuimato Sauce, mustard and pickles to the top buns, then place each burger on a bottom buns.
Serve immediately.
Tip: add a firm fried egg for best results.
