Peel the Hokkaido, remove the seeds and cut into cubes. Dice the feta and peppers as well. Put everything in a bowl and mix well. This mass is not seasoned because the feta has a lot of flavor.
Then cut the onion and sauté in a pan. When the onions are translucent, add the ground beef and fry well. Season generously with salt, pepper and paprika powder.
Then mix the ground beef with the pumpkin mixture and place in a greased baking dish.
