Saute in 1 Tbs. oil for a few minutes.

 

Add enough water to just cover vegetables, cover and simmer on Medium until veggies are all tender.

 

Using a hand potato masher or a hand blender, puree the vegetables to the consistency you want (we prefer a few chunks, but mashing everything makes it quite thick).

 

Salt and pepper to taste.

 

Stir in 1 Cup grated cheddar until melted.
