A fruit, since it has seeds, but vegetables can be made into desserts too. Like rhubarb pie. [ Which is also sweet, like pumpkin pies... The whole debate of fruits and vegetables can be argued either way, but Minato sides with botanists over chefs, only passively picking up recipes through watching or looking them up, nothing at all like a certain sister of his who prepares entire meals and bakes enough to stock her own store. ]

I've never made pie before, but porridge is easy. You cut the pumpkin into cubes, throw it in a pot of rice and water, turn on the stove and walk away. A pumpkin sounds easy to make too. Cut a pumpkin into cubes, throw it in the blender with milk, banana, and cinnamon, turn on the blender and walk away.

[ Only don't actually walk away from the kitchen when you're cooking, keep an eye on your food... ]
