The sweet-salty combination of green olives and caramelised onions adds a lovely depth of flavour to this burger recipe. Plus, the monterey jack goes gloriously gooey when melted.

Ingredients
For the burgers
- 500g British 10% fat beef mince
- 75g pitted green olives, chopped
- 1 green chilli, deseeded, finely chopped
- 1 garlic clove, crushed
- 2 tsp cider vinegar
- 2 tsp soy/tamari sauce, plus extra to serve
- 1 tbsp wholegrain mustard
For the onions
- 2 red onions, sliced
- 2 tbsp olive oil
- Splash cider vinegar
To finish
- Olive oil for brushing
- 100g monterey jack cheese, sliced, or similar
- 4 brioche or sesame burger buns, halved and toasted
- 4 tbsp mayonnaise
- 1 little gem lettuce, separated into leaves, plus extra to serve
- Large handful pea shoots
- A few pickled jalapeño chillies
Method
- Cook the onions with the oil in a frying pan over a low heat for 35 minutes (cover with a lid after 10 minutes). Add the cider vinegar and cook for 5 minutes more. Set aside (see Make Ahead).
- Meanwhile, mix the burger ingredients in a large mixing bowl and season with black pepper. Divide into 4 equal portions, then shape into patties and set aside on a plate or baking tray lined with non-stick baking paper. Chill in the fridge for 30 minutes to firm up.
- Heat a barbecue or griddle pan. Brush the burgers with a little oil, then cook for 4-5 minutes, pressing down with the back of a spatula. Turn and cook for 4-5 minutes or until done to your liking. Add the cheese for the final few minutes of the cooking time – put the lid on the barbecue or put the burgers under a hot grill to melt the cheese.
- Spread the toasted bun bases with mayo and add a lettuce leaf and some pea shoots. Top with a burger, a splash of soy/tamari sauce and the other half of the bun. Serve with the pickled jalapeños and extra lettuce leaves on the side.
