Using cooked grains to make muffins, instead of relying on all-purpose or other types of flour, is an excellent way to improve their nutritional profile and also to give the muffins an interesting texture. And if you happen to have some leftover cooked bulgur in the refrigerator, here's a great way to use it. Chorizo, onion, carrot, parmesan, and mustard seeds lend these muffins satisfying savory flavors, making them a perfect nibble for enjoying with cocktails.
