Storage: Leftovers can be stored in the refrigerator for up to 3 days. Reheat in the oven or microwave.
Substitutions: For a vegetarian version, omit the ham or replace it with sautéed mushrooms or spinach.
Variations: As noted in the original source, you can turn this into a main meal by alternating layers with a spicy minced meat mixture similar to lasagna filling.
Serving Suggestion: Serve with a green salad dressed with a marjoram and vinegar vinaigrette to complement the herbs in the casserole.
