Well not second hand, but with left-over ingredients. I made this using curry powder and turmeric. I diced up some courgette, onion, broccoli, and aubergine. I then added a tin of tomatoes. I added water to it to stop it burning on and to add moisture. I also added a few lentils. The fish was bought today. It doesn’t really matter what sort, but a white fish isn’t too strongly flavoured. I’d added it later as you don’t need to overcook fish. It flaked nicely as I cooked and turned a nice golden brown. Much nicer than using a jar of curry sauce.
