Similar to tofu it can be sliced, cubed or crumbled depending on what your recipe is. In this recipe I use thin slabs for tender and juicy marinated tempeh. Tempeh will also taste best if marinated and cooked before eating, or crumbled in a stew or soup, it is similar to meat/beans. I have been known to cut a full slab in half, then slice the square in half (like splitting a bagel) and eat as a sandwich filling with veggies and sriracha or curry mayo, without cooking first, though cooking the slap would likely improve its taste, since tempeh is made from only partially cooked soybeans that are fermented but not further cooked before packaging.
