Add chopped carrots, seasoning (salt, pepper, oregano, basil, and optional sugar) along with canned tomatoes and tomato paste.

Set to HIGH pressure for 15 minutes and allow to come to pressure, allowing a natural pressure release for about 10 minutes.

Use a hand held immersion blender to puree until smooth.
