UPDATE: It's been 48 hours since we initially published this, and we're declaring no winner. Answers from the original posting included Anepalco's, True Food Kitchen and others we can't remember. The correct response is . . . City Grill in Brea. Specifically, this is a photo of the Greek Toast appetizer. Maybe next time.
Tomatoes, avocados and cheese make for a tasty bite. Where did I eat this colorful meal? Guess away! Standard rules apply: One guess per person per comment. Don't forget to use a valid email address when responding. Weeklings not allowed. Good luck.
