1. Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper or foil. Pat the cod fillets dry with paper towels, then season both sides generously with salt and pepper.
2. Place the seasoned cod fillets on the prepared baking sheet and bake for 15-20 minutes, depending on thickness, until the cod flakes easily with a fork and reaches 145°F internal temperature. Check around 15 minutes if your fillets are thin.
3. While the cod bakes, toast the whole wheat bagels until lightly golden and crispy on the outside but still soft inside. Don’t over-toast or they’ll be too hard to bite through.
4. In a small bowl, mix together Greek yogurt, fresh lemon juice, a pinch of salt, and pepper to make the sauce. Taste and adjust—it should be tangy and punchy.
5. Once everything is ready, spread the Greek yogurt sauce generously on the bottom half of each toasted bagel. Don’t be shy—this is what keeps everything moist.
6. Layer on sliced avocado, arranging it evenly. Add tomato slices, then thin red onion rings. Season each layer lightly with salt and pepper as you build.
7. Place a cooked cod fillet on top of the vegetables. The fish should be flaky and tender, breaking apart slightly as you nestle it on the bagel.
8. Garnish with fresh chopped parsley if you have it, then top with the other bagel half. Press down gently to help everything stick together.
9. Serve the healthy cod bagels immediately while the fish is warm and the bagel is crispy. These are best eaten fresh!

Notes:

• Fresh cod is crucial—it should smell clean, not fishy.
• Don’t overcook the fish—check early and pull when it just flakes.
• Toast bagels well—this prevents sogginess from the sauce and vegetables.
• Build right before eating—assembled sandwiches don’t hold well.
• Season each layer—this makes every component taste better.

Storage Tips:

These healthy cod bagels are best eaten immediately after assembly. You can prep components ahead—cooked cod keeps in the fridge for up to 2 days, the sauce keeps for 3 days, and you can slice vegetables the night before. Store everything separately and assemble fresh when ready to eat. Don’t assemble ahead of time—the bagel will get soggy and the avocado will brown. This is best as a make-fresh meal or with pre-prepped components for quick assembly.

Serving Suggestions:

• Simple Green Salad: Light and fresh to balance the substantial sandwich
• Baked Sweet Potato Fries: Healthy side that adds substance
• Cucumber Salad: Cool and refreshing alongside the rich bagel
• Fresh Fruit: Light and easy for a complete meal
