- Salt and pepper to taste: Essential seasonings for bringing all the flavors together! (Remember, taste as you go!)
- Fresh herbs (like parsley or thyme) for garnish: A sprinkle at the end adds color and freshness! (Chop them finely for a bright finish.)
- Parmesan cheese (optional): A sprinkle of nutty Parmesan is comforting and tasty! (Always use freshly grated—so much flavor!)
