drizzle the oil in a frying pan, add chicken thighs and season with salt and pepper; cook on high heat for 7-8 minutes each side, until caramelised.
mince shallot and garlic; add them in, together with the white wine and crumbed stock cube; keep turning the chicken to prevent it sticking.
once the wine has evaporated, add tomatoes and olives, put the lid on, and cook for 5 minutes, then uncover, stir, and continue to cook for another 5 minutes, until most of the liquid has evaporated
serve with oregano sprinkled on top.
