Wash the potatoes, cut into slices without peeling the skin (if it is young), but if the potato is thick-skinned, then peel it first.
Green beans can be used both fresh and frozen. If the beans are frozen, then defrost them first and drain the water.
Mix potatoes in a separate bowl with sour cream, salt, spices and transfer to a sheet greased with vegetable oil. Put in the oven at 200°C and bake for 15 minutes until half cooked.
Remove the potatoes from the oven, add beans, garlic and sesame seeds to it, mix and put in the oven for another 10-15 minutes until fully cooked.
Serve with a light vegetable salad.
