This is the perfect showcase for fresh, ripe summer tomatoes and basil. Good as part of a brunch or a light lunch or dinner. From the R.S.V.P. Letters to the Editor section of a June 1984 issue of Bon Apetit.1 cup prepared pesto may be substituted for the fresh basil, but I prefer the fresh basil- it makes a less-greasy final product. The recipe was requested from the Elephant's Delicatessen in Portland, Oregon.
