The Almighty Mob Chicken Pie
Add bacon to the chicken pan and fry until crispy. Deglaze the pan with a splash of water. Add the leeks and onion.
Once soft, add the chicken. Stir it in and add a large handful of chopped tarragon. Stir again and flour.
Mix it in, making sure the flour is all absorbed. Pour in milk, splash by splash. Keep stirring until you have a thick pie filling. Season generously with pepper. Remove the pan from the heat.
