Chicken, Leek & Butter Bean Pie Filling questions
Can I use leftover roast chicken?
Simmer the vegetables and potato in the stock for the full 15 minutes first, then stir in the shredded cooked chicken with the butter beans so it only heats through.
Can I use ordinary milk?
Ordinary semi-skimmed milk works in the same way with the cornflour if you don't need it lactose-free.
Can I swap the butter beans?
Cannellini beans work in the same drained weight. Rinse them well, just like the butter beans.
