Crumbled to bits and crisped up in a pan, a block of firm tofu becomes an enticing (and easy) dinner. Breaking up the tofu with your hands like this dramatically increases its surface area, all the better for absorbing the heady seasoning blend of cumin, coriander, and crushed red pepper flakes. Toasting and grinding whole spices sounds a bit much for a weeknight meal, but once you consider how little else there is to do, you’ll willingly go this extra mile. It makes a remarkable difference to the final flavor, taking on a faint smokiness that ground spices, however fresh, aren’t able to match. A note on the onion: White onion offers the mildest, sweetest crunch, but a regular ol’ yellow onion will do just fine in a pinch.
