Step 1

Preheat the oven at 200°C/390°F

Step 2

Peel the potatoes and cut them into wedges or thick slices.

Step 3

Put them in a baking pan. Add the olive oil, oregano, mustard, and lemon juice, and season with sea salt and freshly ground pepper. Mix well to distribute all seasonings and olive oil evenly.

Step 4

Pour one cup of water at the bottom of the pan, cover with aluminum foil, and bake at 200°C for 1 hour until they are soft.

Step 5

Put the ground beef in a bowl. Add the olive oil, oregano, fresh oregano, parsley, vinegar, one teaspoon of sea salt, and plenty of freshly ground pepper. You can add an egg if you like.

Step 6

Grate the onions and tomatoes, directly into the meat. Let all their liquids pour into the mixture.

Step 7

Start mixing, and based on how loose the mixture is, start adding the breadcrumbs. Knead well, but don't overdo it.

Step 8

Cover the mixture and place into the refrigerator for half an hour.

Step 9

Start making the burgers ten minutes before the potatoes reach the one hour of baking (or are close to being soft). Form 10-12 biftekia-burgers.

Step 10

Remove the potatoes from the oven and lay on top of them the biftekia. Bake for another 30 minutes.

Step 11

Check the burgers to make sure they are done to your liking. Remove burgers and set them aside to rest covered with aluminum foil. Increase the heat to 220°C/ 425°F and continue to roast the potatoes for 10 minutes or until they are golden brown with crispy edges and tender inside.

Step 12

Serve immediately with plenty of feta on the table, lemon wedges, and fresh bread.
