Want to keep this Tangy Pepperoncini Relish gluten-free? Super easy! Just make sure to double-check your jarred ingredients like the pepperoncinis and tamed jalapeños. Some brands sneak in gluten as a preservative (I know, sneaky, right?). Look for ones that say gluten-free on the label, and you’re all set. The good news is the rest of the ingredients—fresh peppers, onion, garlic, olive oil—are naturally gluten-free, so you’re already most of the way there. Now you can enjoy all the tangy goodness without any worries!
