Common Mistakes to Avoid

- Ignoring Seasoning: Under-seasoning can result in bland flavors. Always taste your filling before stuffing and adjust seasoning as needed.
- Using Cold Ingredients: Using cold cheese or spinach can affect the melting quality. Allow your ingredients to reach room temperature for best results.
