1. Slice 1 zucchini into ribbons with a vegetable peeler. Combine with 1/4 red onion, thinly sliced, 1 tablespoon thinly sliced lemon zest, and 2 tablespoons each fresh lemon juice and olive oil. Season with salt and pepper and let stand 30 minutes.

2. Meanwhile, season 1 pound chicken cutlets with salt and pepper and broil until cooked through. Let cool, then shred and add to marinated zucchini along with a handful of chopped toasted almonds and fresh parsley. Cut 1 loaf Italian bread in half horizontally and hollow out. Make a sandwich with chicken mixture (including juices) and romaine lettuce leaves.
