Preheat the oven to 425°F, and spray a large baking sheet with cooking spray (or line with parchment paper).
In a large mixing bowl, combine the saltine crumbs and parsley. Stir in the yogurt, red pepper, water, lime juice, 2 to 3 dashes of hot sauce, salt to taste, and the crab meat. Lightly mix the egg whites with a fork and stir them in. It is important that the mixture be thoroughly combined.
Using your hands, form 16 crab cakes and arrange them 1-inch apart on the prepared baking sheet. Bake for 10 to 12 minutes, turning the crab cakes with a spatula after 6 minutes. The crab cakes are done when they are browned and cooked through.
