The star of the show here is the roasted red pepper, which is very easy to make. You will cut a red bell pepper in half, then roast it dry (no need for oil or salt here!) cut side down until it is softened and the skin is charred.

After removing them from the oven, place the charred peppers in a bowl and cover with a plate or saran wrap. This will trap the heat and steam, and loosen the charred skins making them so easy to peel.

You can chop the peeled roasted red peppers using a knife, food processor or even by placing it in the bottom of a mason jar and chopping with your immersion blender.
