Prepare the flaxseed mixture by mixing 1 tablespoon of flaxseed meal with 2 tablespoons of water and set aside for 5 minutes.

In a large mixing bowl, combine the mashed chickpeas, cooked lentils, oat flour, chickpea flour, and dry spices. Mix thoroughly.

Add the onion, garlic, olive oil, soy sauce, tomato paste, apple cider vinegar, and flaxseed mixture to the bowl. Mix until a cohesive dough forms.

Divide the dough into four portions, roll each into a log, and wrap tightly in parchment paper or aluminum foil.

Steam the sausages in a pot for 30 minutes, ensuring they are not touching each other.

Let the sausages cool slightly and unwrap them. Optionally, pan-fry for 2-3 minutes on each side for a crispy texture.

Slice, crumble, or serve whole in a bun with toppings. Enjoy your sausages!
