Onions peel and cut into slices. Peel and wash the potatoes and cut them into halves or quarters depending on their size. Spread both around the roast after about 1 hour. Season with salt and pour on 1⁄4 l water.
Continue to roast, brushing the roast from time to time with roast mixture or pouring over.
Cut the pumpkin into quarters and remove the seeds. Peel quarter and cut into slices. Spread the pumpkin around the flesh about 20 minutes before the end of the frying time, season with salt and pepper. Finish cooking and serve.
