For the roasted red peppers you could always use fresh red peppers and roast and peel them yourself, but it is much easier to just buy roasted red peppers in a jar, especially because you really can’t tell the difference. For this recipe, I use about 1/2 of an 8 ounce jar of roasted red peppers and then I just be sure to pat them as dry as possible with paper towels before incorporating into the recipe.
