Then spread the seasoned minced meat evenly over all slices of toast and bake for 10 minutes at 175 °C (350 °F) using normal oven settings (on a baking sheet lined with baking paper).

Remove the baking sheet and top the toast with onion rings, tomato slices and cheese slices.

Put back in the oven for another 10 minutes, but only at 150 °C (300 °F), otherwise the toast will be too dark. The cheese should be golden brown and slightly melted.
