Tempeh definitely has a stronger flavour than tofu, so if you're not a fan of its bitter, nutty taste, how you cut your flat block of tempeh matters. You want to either cut it into small cubes, or crumble it. This will allow the tempeh to soak up more of the seasonings and sauces you're adding to the dish.
When you crumble tempeh, it can taste and look a lot like ground beef — it may even fool your meat-loving friends! You can use it in red sauce over pasta, add it to chili, or use it as filling for tacos.
