How to Make It
Cut bell peppers in half lengthwise; discard seeds and membranes. Place pepper halves, skin sides up, on a foil-lined baking sheet; flatten with hand. Broil for 20 minutes or until blackened. Place in a large zip-top plastic bag; seal. Let stand 20 minutes. Peel and cut into (1/4-inch-wide) strips.
Combine juice and next 5 ingredients (through garlic) in a medium bowl, stirring well with a whisk. Add peppers to bowl; toss gently to combine. Cover and chill overnight. Sprinkle with cilantro before serving.
