Place bell pepper on a baking sheet and broil, turning every 4 to 5 minutes, until the skin is blackened and blistered on all sides, 20 to 25 minutes. Transfer the pepper to a bowl, cover, and let steam until the skin is loosened, about 10 minutes. Uncover; when cool enough to handle, remove the skin. Discard stem, seeds and ribs.
Place the roasted pepper and half the tomatoes in a blender; and onion and oil and puree until smooth. Transfer to a large metal bowl. Puree the remaining tomatoes until smooth and add to the bowl; stir to combine. Refrigerate the gazpacho until chilled, at least 2 hours. Season with salt and pepper. Serve garnished with jalapenos, if desired.
Make Ahead Tip: Cover and refrigerate for up to 1 day.
Tip: To peel tomatoes: Make a small X in the bottom of each tomato and plunge into boiling water until the skins are slightly loosened, 30 seconds to 2 minutes. Transfer to a bowl of ice water for 1 minute. Peel with a paring knife, starting at the X.
Cut Down on Dishes: A rimmed baking sheet is great for everything from roasting to catching accidental drips and spills. For effortless cleanup and to keep your baking sheets in tip-top shape, line them with a layer of foil before each use.
