Vegan Two-Layer Mojo Seitan Tacos

1 Make the marinade. First, take the whole head of garlic, peel all of it, then either add all the garlic cloves to a  food processor and pulse for a few seconds to turn into a paste. Or using a mortar and pestle smash the garlic into a paste. 
2 Add the garlic paste to a medium sized bowl. The add the remaining marinade ingredients to the bowl. Whisk to combine. 
3 Now add the seitan strips to the bowl with the marinade, stir to coat all of the seitan in the marinade. I like to marinate over night, or the morning of. However, I recommend marinating for at least an hour or 2. Stir every once in a while to make sure the marinade is evenly distributed. 
4 Once you are ready to make the tacos. heat a non stick skillet on medium high. Then pour the seitan, marinade and all into the skillet. Saute, reducing heat as needed until the marinade has thickened and the seitan is cooked through. About 5-10 minutes. 
5 While the seitan is cooking, spread each soft tortilla all over with guacamole, then fold it around the hard taco shells. I like to heat up my tortillas and shells first. 
6 Then, when the seitan is done, fill the taco shells with seitan, top with crushed plantain chips, cilantro, or whatever you want!
