Start by taking that softened cream cheese and plopping it in a medium-sized mixing bowl. The softening is important; otherwise, you'll just end up with a clumpy spread that’s hard to work with. Add in the Italian dressing, Italian seasoning, garlic powder, and a pinch of salt and pepper. Stir it all together until smooth and creamy, making sure every bit of that cream cheese is mixed well. Toss in the finely chopped pepperoncini and roasted red bell peppers, folding them into the spread for added zing and sweetness.
