Heat oil in a saucepan over medium-high heat, add chorizo and stir occasionally until browned (1-2 minutes). Add onion and garlic and stir occasionally until tender (3-4 minutes), add beans, tomato, stock and herbs, season to taste and simmer until liquid is well-flavoured and reduced by half (4-5 minutes). Remove herbs, add vinegar and season to taste.
Meanwhile, preheat grill to high. Drizzle bread slices with a little oil and grill, turning once, until golden (1-2 minutes each side). Rub with cut-side of garlic, top with bean mixture, scatter with oregano and serve hot.
