In a large pot, saute onion, celery, red pepper, and carrots, till onion becomes translucent. Add veg. broth, tomatoes, oats, seasoning, and copped fresh basil. Bring to a boil then reduce heat and simmer till carrots and celery is soft...stirring frequently to keep oats from sticking to the bottom of the pot. Cool slightly and pour little at a time into blender, blend till smooth. Return blended soup to pot and reheat...add more seasoning if necessary.
