Add the oil, garlic, chilli and oregano to a pan and cook for 2 minutes over a medium heat until fragrant.
Stir in the olives and capers, with the tablespoon of brine from the jar. Pour in the passata and sugar.
Stir in the butter beans, then simmer over a medium-high heat for 10–15 minutes, stirring occasionally.
Remove from the heat and season with salt and pepper. Scatter over the parsley just before serving and drizzle with a little extra olive oil.
