Salad in an Apple

Use an apple corer to take out the core, than cut out more flesh from the inside using a small knife. Trim the bottom if necessary in order for the apple to stand straight and firm. Mix onion, bell pepper, lettuce and lemon juice, put inside apple. Whatever you can’t fit into the apple can go around the apple. Squeeze some lemon juice on it. Put walnut and raisins on top of the salad.
