Combine softened cream cheese, pepperoncini peppers, pepperoncini juice, garlic powder and dried oregano in a small bowl and stir thoroughly to combine all the ingredients. Season with salt and pepper as desired.
Transfer dip to the serving container and chill in the fridge while the bagel chips are prepared.
Split bagels in half and slice each half into 1" wedges. Combine bagel pieces in a medium bowl with olive oil, garlic powder, dried oregano, and salt. Toss together to make sure all of the bagel pieces are covered evenly with oil and spices.
Spread seasoned bagel pieces onto the prepared baking sheet and bake in preheated oven for approximately 15 minutes, tossing the bagel pieces halfway through cooking. Bagels pieces should be lightly browned and crispy.
Cool bagel chips completely and serve with the chilled dip.
Use softened room temperature cream cheese to help make sure all of the ingredients mix together well. Whipped cream cheese may be used, but the dip with be looser.
Whole jarred pepperoncini peppers may be used and sliced or jarred sliced pepperoncini peppers can be used to shorten prep time.
Onion or everything bagels may be used instead of plain bagels for extra flavor and texture.
Dip can be made up to 2 days ahead of time and stored in an air tight container in the refrigerator.
Bagel chips can be made earlier in the day and stored in a zip top bag after cooling. It's recommended not to prepare them too far in advance as the chips will start to soften in the bag after a few hours.
