Daddima,
a South African friend gave me this recipe that sounds similar, she called it Cheese Pie. it uses cubed bread, instead of breadcrumbs, and paprika instead of mustard.
Cheese Pie
4-6 ozs cheese, grated
1 oz marg
3/4 pint milk
2 egg , beaten
2-3 slices white bread, cut into small squares
* optional, garlic paste,
paprika
1 round pyrex dish
Pre heat oven to 180
Using the one dish for economy - saving washing up.
( if using garlic paste, put into bowl before heating milk.)
1/ Place milk and marg into dish, then iinto microwave for 1.5 minutes
sufficient to melt marg. Stir.
2/ Add diced bread, lightly stir into milk mix.
3/ Stir in beaten eggs and 3/4 of grated cheese.
4/ Sprinkle remaining cheese on top and lightly dust with paprika for a
dash of colour.
5/ Place dish in oven, middle shelf, and bake for approx 45 minutes.
I you feel that it is cooking too quickly, lower heat after 30 minutes.
The pie will rise, and the top willhave a light crusty look and a sort of souffle texture underneath.
Serve with salad and sliced tomatoes.
