Peel the potatoes and cut them into even-sized chunks. In a saucepan, boil the potato pieces in salted water until they are tender, which should take about 15-20 minutes.

While the potatoes are cooking, place the spinach in cream in a separate pot over medium heat. Allow it to wilt, stirring occasionally, until it is heated through and well combined.

In a frying pan, heat a little oil over medium heat. Once hot, add the fish sticks and fry them according to package instructions until they are golden and crisp.

Once the potatoes are cooked, drain them and return them to the pot. Mash the potatoes, then combine them with the wilted spinach mixture, stirring until everything is evenly incorporated.

To serve, add spinach puree to a plate, topped with the crispy fish sticks. Enjoy your meal!
