Snap off the tough ends of asparagus. Steam asparagus, covered, 2 minutes or until crisp-tender.
Cut bell pepper in half lengthwise; discard seeds and membranes. Place bell pepper halves, skin sides up, on a foil-lined baking sheet; flatten with hand. Broil for 10 minutes or until blackened. Place in a zip-top plastic bag; seal. Let stand 15 minutes; peel. Place the bell pepper, honey, juice, salt, and ground red pepper in a blender; process until smooth. Combine bell pepper mixture and mayonnaise in a small bowl.
Warm the tortillas according to the package directions. Spread 1 tablespoon of the mayonnaise mixture evenly over each tortilla. Layer each tortilla with 1 romaine leaf, 2 turkey slices, 1/2 cup sprouts, and 6 asparagus spears; roll up. Serve with remaining mayonnaise mixture.
