taco bell guacamole?
Best I can find at the moment... Guacamole is usually vegan, most recipies I've seen are anyway.
"TACO BELL: If requested, Taco Bell will send a list of their menu items that are suitable for vegetarians. Under their lacto-ovo heading, they list the following: Pintos & Cheese, Bean Burrito, Bean Tostada, Mexican Rice, Seven Layer Burrito (no sour cream), Cheese, Gordita Shells, Creamy Jalapeno Sauce, Creamy Lime Sauce, Pepper Jack Sauce, Baja Sauce, Fiesta Salsa, Red Sauce, Hot/Mild/Fire Sauce, Green Sauce, Pizza Sauce, Guacamole, and Taco Shell. Under their vegan heading, they list: Bean Burrito (without cheese), Bean Tostada (without cheese), Mexican Rice (without cheese), Seven Layer Burrito (no sour cream, no cheese), Hot/Mild/Fire Sauce, Fiesta Salsa, Red Sauce, Soft Tortillas, Pizza Sauce, Green Sauce, Guacamole, and Taco Shell. Taco Bell used to have two different distributors for the Mexican Rice. They are no longer using the distributor which had milk derivatives in the rice. NOTE that the sour cream does contain gelatin, which is animal based.
Taco Bell stressed that while the ingredients listed above may be categorized as acceptable for certain types of vegetarian diets, all ingredients are handled by employees in common with other ingredients which may not be acceptable to certain types of vegetarian diets."

Things must have changed since you've had it. It tastes great, or at least at the Taco Bells I've gone to. It tastes just like fresh home-made guacamole, and I only make guacamole at home with fresh avacado along with some other minor ingredients. It's surely vegetarian, and in all likelyhood vegan.
