Okay, so I've never had Chilli Taiyo, and I can't find an ingredent list of it, but what it seems to be is canned tuna flakes packed in chili oil. This is what I would imagine a good vegan version would be. Light on the oil for preference.
Add chickpeas. soy sauce, lemon, onion flakes, nooch, and kelp/dulse to a small food processor. Chop a few times until the chickpeas are flaked, and the spices are mixed well.
Transfer to a mixing bowl and add the chili oil. Mine was very spicy, and I don't like a lot of oil in my foods, one tsp was enough.
