To store this as a Dump Bag recipe just prep the vegetables and store in a bag in the freezer ready to be cooked. When you're ready to cook, throw into the slow cooker, add the water and stock and then finish as per the recipe (don't freeze the cream). This is SO USEFUL if you have veggies that are about to go off in the fridge, but no time to do anything with them today. Chop and prep them for another day. It's also worth noting that as this recipe is vegetarian, there's no need to defrost before slow cooking - win!
