I've seen lots of low-carb cracker recipes, most of which involve a lengthy process of mixing a dough, rolling it out, cutting out individual crackers, and so forth. These are significantly easier: just bake grated cheese with seasonings until crisp. I baked grated Asiago and cracked rosemary in silicone mini-muffin trays so that they came out perfectly round. If you use mini-muffin trays, they MUST be silicone, otherwise they will stick. If you do not have one, you can mound up the cheese on a baking sheet lined with parchment paper. While cheese is somewhat calorically-dense, each crisp has only about a teaspoon of cheese. Thus, a small amount of cheese is stretched a long way.
