1. Preheat your oven to 350°F and grease baking dish with olive oil—essential for fish-based recipes.
2. Mash sardines with fork until broken up but still textured, preserving some small pieces.
3. Add cooked quinoa, grated carrot, and chopped spinach, creating beautiful color medley.
4. Mix in egg and olive oil until everything holds together when pressed (if your pup can wait that long).
5. Spread evenly in greased baking dish, pressing gently for uniform thickness.
6. Bake for 20-25 minutes until set and lightly browned on top.
7. Cool completely before cutting into squares—prevents crumbling and easier serving!

Notes:

• Always let cool completely for clean cutting and safe serving temperature
• Amber prefers these firm enough to hold square shape but tender for easy chewing
• If mixture seems too wet, add oat flour gradually; too fishy, rinse sardines more thoroughly

Storage Tips:

• Store in refrigerator for up to 5 days in airtight containers—fish needs careful storage
• Cut into meal-sized portions for easy serving throughout the week
• Freeze individually wrapped for up to 2 months for longer storage

What Makes This Recipe Special:

These squares combine sardines’ concentrated omega-3 fatty acids with quinoa’s complete amino acids and vegetables’ essential vitamins, creating superfood nutrition that supports heart health, brain function, coat shine, and immune strength. Unlike synthetic omega-3 supplements with questionable bioavailability, every bite delivers real ocean nutrition with natural co-factors that enhance absorption and utilization.
