Key Ingredients & Substitutions
1. Cod Fillets
- Why cod? Mild flavor and flaky texture make it ideal for absorbing Mediterranean spices. Opt for wild-caught Atlantic cod for sustainability 912.
- Substitutes: Halibut, hake, or tilapia work well (adjust cooking time for thinner fillets) 1112.
2. Mediterranean Vegetables
- Tomatoes: Cherry tomatoes add sweetness; canned diced tomatoes work off-season 16.
- Olives: Kalamata or black olives lend briny depth. Swap with capers for a tangy twist 1011.
- Aromatics: Garlic, red onion, and lemon zest form the flavor base.
3. Seasonings
- Herbs: Oregano, thyme, and parsley (fresh or dried) evoke coastal flavors 511.
- Heat: Chili flakes or paprika add subtle warmth (optional) 1012.
4. Healthy Fats
- Olive oil: Rich in monounsaturated fats, it enhances both flavor and nutrient absorption 712.
- Butter: Optional for a richer sauce; omit for dairy-free diets 610.
