Method

1. 1
   Preheat your oven to 200ºC/Gas mark 6.
2. 2
   Place the mince in a non-stick wok or saucepan and dry fry for about 5 minutes until browned (this means you don't have to add any extra oil or fat to the pan and a little fat will come out of the mince which will help the meat to brown).
3. 3
   Add the onion and garlic and cook for 2 - 3 minutes.
4. 4
   Add the courgettes, sweetcorn, chopped tomatoes, tomato puree and ketchup, herbs and black pepper.
5. 5
   Cook gently over a low heat for a few minutes. Add the cubed cheese into the mixture and carefully transfer into an ovenproof dish.
6. 6
   Top with the oven chips and sprinkle with the grated cheese.
7. 7
   Cook for approximately 20 - 25 minutes until the chips are cooked and browned.
