This is a dish we had a lot growing up. Mum would use potato chips for a crunchy topping, but I hardly ever have those in the house. It is relatively quick, and inexpensive and can be stretched even further with a green salad.

A great recipe, easy, tasty and fast! We loved the crushed chips on the top (a good way to use the small chips no-one wants to eat). We are a family of 6 and it made 8 generous serves. I served it with steamed broccoli and garlic bread - go the carbs!!!! Thanks for posting Sassy Syrah.

This was really tasty! That little sprinkle of cayenne pepper made this meal. I didn't change a bit of this, it was cooked to perfection and loved by the whole family (kids aged 7 &5). Thanks, will definitely make again.
