You can swap and change the veg in this recipe for whatever's in the fridge
In a little vegetable oil, fry the onion gently for 10 minutes in a large pan then add the remaining vegetables and stir together. Add the curry base sauce and simmer gently for around 25 to 30 minutes, taking care not to overcook the vegetables. If the sauce becomes too thick, add a little water to give you the desired consistency.
