Heat up a pan on medium heat.
Cut up the butternut squash into small cubes (they don't need to be perfect, they will be mashed shortly, but the smaller they are, the faster they will cook).
Once the pan is hot, add in the butternut squash along with a splash of water, cover the pan and let it cook until the squash is completely cooked through.
Transfer the cooked squash to a bowl, add in the ricotta, and mash it into a paste-y filling. Add nutmeg, salt, and pepper to taste.
Place a small scoop of filling into the center of a dumpling wrapper. Wet the edges of the wrapper with water. Fold the dumpling in a half moon shape. Bring both edges of the half moon together until it makes a tortellini like shape. I was able to make roughly 8 dumplings from this amount of filling.
