Pop the chicken breasts into sandwich bags, then use a rolling pin to beat each breast until it’s 1cm thick.
Add the cornflour and Chinese 5 spice into a bowl and mix well. Coat the chicken breasts in the cornflour.
Heat some cooking oil in a large frying pan over a medium to high heat. Cook the chicken until it’s golden brown and crispy on both sides.
Whilst it’s cooking, make the sauce. Add the soy sauce, mirin, sriracha, sweet chilli sauce, garlic paste, and ginger paste into a bowl or a jug, and mix until well combined.
Pour the sauce over the chicken and cook until the sauce is bubbly and sticky.
Dish it up with your choice of side. This will go well with some sticky rice, although I served it with some salt & pepper potato wedges and some greens. Spoon the sticky sauce over the chicken then finish with a sprinkle of sesame seeds, and some sliced spring onion.
