Although you'll see it's win with an asterisk if you read on. Below, you'll find a recipe from Veracruz that I've been cooking since the early 1980s. I originally got it from GOURMET or BON APPETIT. A quick search in Epicurious.com yields Shrimp Veracruz which includes olives as an ingredient, along with the instructions to serve with cold Mexican beer.
