Mos "Soy Sea Burger -Soy Fish-Style Fries-" Looks Like the Real Thing! A hamburger made mainly from vegetables and grains. If you eat it without knowing anything about it, you may not even notice it.
I actually tried the "Soy Sea Burger - Soy Fish-Style Fries", a limited-time-only menu item available at Mos Burger. This burger does not use any animal ingredients as its main ingredients and is made mainly from vegetables and grains.
