I just use broccoli, cauliflour, courgette, carrots, peppers, green beans, chopped tomatoes, onion, garlic nd any other veg i need to use up.
Diced the onion and garlic and fry in fry light. Add the rest of the veg (start with the firmest like carrots and brocc and finish with softest) and add any spices you want. I use a tikka spice blend I got from asda and mustard seeds mostly. Add the chopped tomatoes and leave to cook until all the veg is softened. Then I remove about half the mixture and blend before stirring back in to make the sauce really thick!
Its delicious and is 0pp!
