A bit of zing is added to Chipotle Shrimp Cocktail thanks to the chopped chipotle peppers in adobo sauce that's added to this appetizer.
Cut onion and bell peppers into thin strips; layer with shrimp in a large zip-top plastic freezer bag.
Whisk together ketchup and next 5 ingredients; pour over shrimp mixture. Seal and chill 12 to 24 hours, turning bag occasionally. Serve using a slotted spoon.
