Slice the tempeh into thin slices and let the pieces sit in the marinade for 10-15 minutes (overnight if you can).
Sautee tempeh in a pan with a light layer of olive oil. Cook until desired crispiness. Toss in any remaining marinade you have left over and let simmer.
Remove tempeh slices from heat and place on a paper towel. Can dice if desired or serve as is.
For the tempeh, I used Lightlife's brand which can be found at many health food stores.
If you want to make a jar of the marinade so you don't have to remix every time, increase the measurements 1:1 to each serving you'd like to store away. Example: for 4 servings, do 4x as much of each ingredient.
