Place the chia seeds, flaxseeds, and sea salt in a bowl. Add the hot water, stir, and let rest for at least 15 minutes until the mixture thickens into a gel.

Once thickened, add the almond flour and mix well. Knead with your hands until a dough forms. Lightly wet your hands to prevent sticking.

Roll out the dough between two sheets of parchment paper until thin and even.

Transfer to a round 15 cm baking pan, pressing it evenly into the base.

Pre-bake at 200°C (390°F) for 10–15 minutes. Remove from the oven and let cool.

In a pan with olive oil, sauté the onion (sliced) until soft. Add the bacon strips and cook until slightly golden.

Add the spinach and cook until wilted. Set aside to cool.

In a bowl, beat the eggs and mix with cottage cheese. Add the cooled vegetables and bacon, stirring to combine.

Pour the mixture over the pre-baked crust.

Bake at 180°C (350°F) for about 30 minutes, until set and lightly golden.

Let rest before slicing and serving.
