Chop the first 3 ingredients (potentially reserving 1 cup basil leaves) in
food processor. Add mayo and tofu and blend until creamy. While blending add
remaining ingredients, stopping to scrape down sides with spatula (and test for
taste) as necessary.
I originally used about 2 cups of basil and the final product didn't seem
quite basil flavored enough for me and tossed another cup in at the end. Then it
was perfect. (Makes about 1 1/2- 2 cups)
