Ingredients
- 1 tbsp olive oil
- 1 onion, finely sliced
- 150ml Irish stout
- 1 tbsp sugar
- 2 M&S Our Best Ever beef burgers
- 2 M&S Big Cheese Burger Melts
- 2 brioche burger buns, halved
- 8 green and red pickled chillies, sliced
Method
Step 1
Heat 1 tbsp oil in a non-stick frying pan over a medium-high heat. Add the onion and cook for 12-15 mins, or until softened and starting to caramelise.Step 2
Add the stout and sugar and cook for a further 5 mins, or until all the liquid has evaporated. Remove from the heat, season with salt and pepper to taste and set aside.Step 3
Place another non-stick frying pan, with a lid, over a medium-high heat. When hot, add the burgers and flatten with a fish slice. Cook for 2 mins on each side. Top each with a Big Cheese Melt, add a tiny splash of water to the pan and cover with the lid. The steam will help the cheese melt.Step 4
Lightly toast the buns, then place the cooked burgers onto the bases. Top each with the onions and chillies, then top with the other bun halves. Serve with your favourite condiment.
