Use your multi-functional pressure cooker to quickly whip up a batch of cocktail wieners that are swimming in a tasty, yet mild, chipotle-orange sauce.
Combine ketchup, chipotle salsa, orange zest, orange juice, Worcestershire sauce, onion and cilantro in a bowl. Mix chipotle-orange sauce until thoroughly combined.
Turn on a multi-functional pressure cooker (such as Instant Pot®). Add the chipotle-orange sauce and cocktail wieners and stir to blend. Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 1 minute. Allow 10 to 15 minutes for pressure to build.
Release pressure using the natural-release method according to manufacturer's instructions, 10 to 15 minutes. Release remaining pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid.
Sprinkle cilantro on top and serve immediately, or switch the multi-functional pressure cooker to slow cooker mode to keep warm.
