Ingredients Notes
The key to a great dish is using fresh and quality ingredients. Opt for firm zucchinis that are bright green and free from blemishes. If tuna isn’t to your taste, canned salmon makes a wonderful substitute. Using cheese like cheddar or mozzarella adds a creamy texture, while fresh herbs like dill or parsley can enhance the flavors significantly.

Variations & Substitutions
