The slow cooker in the best thing for a stew. Cook off any type of meat throw it in, add plenty of liquid using passata as a base then add any veg you want to and spices. This is one of the only ways I will actually eat veg, because it is cooked slowly for a long time the contents of the pot just fall apart. Really tasty with roast potatoes. If you want to add a it of spice to the pot serve with rice.
