Brill invention! I buy from Asda frozen chopped red onions. Frozen mixed veg. Frozen Spinach. Bag Kale, bag Watercress, bag Parsley and bags of fresh herbs. The Kale, Watercress, Parsley and herbs which are not frozen I put them into small amounts into individual bags and pop them in the freezer. When I make soup in the machine I put some of the onions and mixed veg into the machine along with some boiling water this helps to defrost them. Then I put whatever I fancy, perhaps some Kale, Watercress, Parsley. A tin of chopped tomatoes, tin of green lentils, some tomato puree and four teaspoons of Marigold veg stock powder. Fill the machine up to the max mark with boiling water. When I use the Kale, Parsley, Watercress & herbs I make smooth soup as it would be stringy if I didn't. If I'm making chunky soup I leave these items out and can put a tin of chick peas in or tin of Kidney Beans or even a tin of corn. No need to stand and stir! Just plonk the lid on, switch on and the machine will do it's own thing. Delicious soup for about four days! I'm so glad someone mentioned soup making machines on here or I would never have known they existed. I have told family and friends about it and they are all delighted too!
