This sandwich alone can turn a bacon-loving carnivore into a piglet-loving vegan. Tempeh is one of my favorite meat substitutes because it is high in protein and low in fat. The marinade gives it an irresistible sweet and smoky flavor!
Technique tip: To make the "bacon" super flavorful and savory, use up all that good marinade!I like to add a lot of the marinade straight into the pan when I'm cooking it because why throw out the flavor source?
Swap option: To make it gluten free, use gluten-free tamari in the "bacon" marinade and serve on gluten-free bread.
For the "bacon":
Mix oil, maple, tamari, spices, herbs and salt in a bowl. Add tempeh and toss until coated. Transfer to a sealed plastic bag or container and marinate for about 10 minutes (this step can be done ahead and left to marinate overnight).
Remove tempeh from marinade and pan-fry in a nonstick skillet until lightly browned. Add a little reserved marinade to the pan for flavor.
For the aioli:
Blend all ingredients in a blender until smooth.
Layer bread, aioli, bacon, avocado, lettuce, tomato and onion.
