1. Start by cooking the quinoa pasta according to the package instructions. Once cooked, drain and set aside to cool slightly.
2. While the pasta is cooking, preheat your oven to 180°C (350°F).
3. In a pan over medium heat, add the olive oil. Once warmed, add the finely grated zucchini and sauté for about 3-4 minutes until softened. Remove from heat and let cool.
4. Meanwhile, place the salmon fillet in a shallow baking dish, season lightly with a pinch of salt and black pepper if using. Bake in the preheated oven for 12-15 minutes or until the salmon is cooked through and flakes easily with a fork. Allow it to cool down before flaking it into smaller pieces.
5. In a large bowl, combine the cooked quinoa pasta, sautéed zucchini, and flaked salmon. Mix gently but thoroughly to avoid breaking the pasta too much.
6. Using your hands, form small bite-sized balls or patties from the mixture, varying the size according to your toddler’s preference.
7. Place the bites on a lined baking tray. Optionally, you can brush each bite lightly with more olive oil.
8. Bake in the oven at 180°C (350°F) for an additional 15-20 minutes until golden and slightly crisp on the outside.
9. Let the bites cool down before serving them to your toddler.
