In a large bowl, mix together softened cream cheese and sour cream until combined and smooth
Stir in salsa and shredded cheddar cheese.
Lay out one large tortilla onto a clean surface.
Spread about 1/3 cup of cream cheese mixture (more if you like a thick filling) onto one half of the tortilla.
Roll up tight, leaving ends open.
Repeat with all remaining filling and tortillas.
Now, you can either slice them into 1 1/2 inch circles and serve with salsa OR cover them in plastic wrap and let chill until ready to use.

Notes
You can spread the filling over the entire tortilla instead of just half. You'll just get half the amount of the pinwheels but if you like more filling, that is the way to go.
They stay good in refrigerator up to 2 days.
Use any of your favorite shredded cheese for this. A Mexican-style blend would also be delicious.
For an extra kick of flavor, try adding a little bit of sliced green onion to the cream cheese mixture before spreading.
