Mini beef sliders

Method

1. Heat a glug of sunflower oil in a frying pan over a medium heat. Add 1 finely chopped onion and 1 crushed garlic clove, then fry for 8-10 minutes until the onion has softened and begins to turn golden. 
2. Transfer to a mixing bowl and add 500g minced beef, 1 medium free-range egg yolk, 1 tbsp rinsed and drained capers, 60g fresh breadcrumbs, a handful of chopped fresh flatleaf parsley and 2 tsp dijon mustard. Season and mix everything together thoroughly, then shape into 8 equal patties. 
3. Heat a pan with a glug of sunflower oil over a high heat, then fry the patties for 4-5 minutes on one side. 
4. Flip the patties and cook for another 4-5 minutes or until cooked to your liking. Serve in mini bread rolls, with rocket, sliced avocado and cucumber, chopped spring onion and lemon wedges, alongside chips, if you like.
