Roughly chop all ingredients (potimarron, pear, onions, garlic).
In a pan, heat some oil. Saute the onion and the garlic for 1 to 2 min.
Add the squash and pear pieces, then, the water. Add salt and pepper.
Close the pan and cook it until the squash is tender (about 30 minutes with a pressure pot, longer otherwise).
Once cooked, stir everything in a blender. Add water as needed (I like thick soups, but you can add more water depending on the texture you want).
Serve with some cream and roasted pumpkin seeds, if you like.
