Heat oil in a large nonstick saucepan over medium heat.
Add onions and celery to the saucepan.
Stir the onions and celery frequently and cook until they are soft but not browned, which should take about 4 minutes.
Pour the broth into the saucepan and add the cauliflower.
Increase the heat to bring the mixture to a boil.
Once boiling, cover the saucepan and reduce the heat to simmer. Cook until the cauliflower is tender, which will take about 10-15 minutes. Then, remove the saucepan from the heat.
Transfer the mixture into a blender, but save some cauliflower pieces if you want some chunks in your soup.
Blend the mixture until it reaches your desired texture.
Stir in the half & half and nutmeg into the blended mixture and blend again.
Serve the soup and top it with grated cheddar cheese.
