Absolutely love this dish. Very easy to make, but you have to have good quality beef ( i am using eye fillet).
Beef- 600 g fillets, cut in 3 cm pieces, trimmed and slightly hammered.
Potatoes- 2 large, sliced in thin slices
Onions- 2 large cut in half rings
Cheese- 150 g grated
Mayonnaise- 1/2 cup
Put salt and pepper on a hammered beef slices and let it sit in a fridge for 15 minutes.
Heat an oven to 200C.
Get a large tray drizzle some oil on it and start layering.
First put beef (mske sure there is enough space between the pieces) then put onions (separated) , potatoes 3-4 pieces on each fillet, spread mayonnaise and finish with grated cheese. Cook in the oven until cheese is nicely colored.
