Combine all the ingredients except the bread crumbs and toasted bread in the bowl of a food processor. Pulse on and off until smooth. Add bread crumbs little by little until you obtain a spreadable mixture. Keep in mind that the mixture will become thicker as the bread crumbs absorb moisture. Spread on toast and serve at once.;
