Preparation -- 20 minutes

Fill the medium-sized pan with water and salt and bring to a boil. Peel and rinse the potatoes and cut them into thin slices. Cook the potato slices for a few minutes. Meanwhile divide the cauliflower into smaller florets.

Remove the potato slices from the water using a skimmer and add them to the oven dish. Bring the water back to a boil and cook the cauliflower florets for a few minutes.

Pre-heat the oven to 190 degrees celsius or 375 degrees fahrenheit.

Divide the cooked cauliflower florets over the potato slices and pour the egg-cream mixture over the oven dish. Divide a thick layer of grated cheese over the top along with a handful of panko and a few cubes of butter.
