This soba noodles recipe is a bit like vegan yaki soba, but without the fried soba. When baking, these Japanese buckwheat noodles often fall apart, so we'll leave that out. In this soba recipe, make sure you let the eggplant soften a bit first, and then cook the soba separately. By the way, the sauce with this vegan soba recipe is invincible, so make sure you have all the ingredients at home. The secret of this Japanese sauce? All the flavors come back in it. Soba contains a relatively high amount of protein, and so does tahini. The eggplant does look a bit like meat. If you want to make it even more of a protein-rich meal, add seitan to these delicious soba noodles!
