Just like meat, marinating your tempeh will help infuse it with flavour. This one-pan tempeh and sweet potato recipe involves marinating the tempeh cubes in tamari, maple syrup, ground ginger, and cumin. If you're a fan of spice, don't feel shy about adding a little kick! Marinate your tempeh for at least 20 minutes before cooking, but you can even leave it in the fridge overnight for a stronger flavour.
