Passover (Pesach).
We eat everything except leavened products. Not only matzah. But the Question meant to ask: of all types of baked goods, why do we eat only matzah. And the answer is that it is a Torah-command (Exodus ch.12), in commemoration of the unleavened matzah which our ancestors ate on the night before they left Egypt (ibid).See also the Related Link.More about Passover and the Seder meal
Most matzah is made from wheat, so most matzah has gluten, and most matzah balls are made from commonplace matzah meal. Gluten-free oat matzah is available. if you make your matzah meal from oat matzah, and then make your matzah balls from oat matzah, then they will be gluten free.
Matzah ball soup was traditionally eaten during the holiday of Passover. Today, people will eat this traditional dumpling in soup year round.
That depends upon if you're asking about a recipe or about eating matzah as part of the Torah-command. In recipes, you'll just have to experiment, though in principle the answer is Yes. Break up the flat matzah, and in effect you now have farfel. For the Torah-command of eating matzah itself, flat matzahs should be used, except for someone who is not able to eat it that way.
Some creative recipes that use matzah meal as a key ingredient include matzah ball soup, matzah crusted chicken, and matzah brei.
There is no prohibition against carbs during Passover. There's matzah, matzah products (meal, cake meal), products made with potato and tapioca starch, potatoes, and other items.

The israellites agreed to follow goods
Potato starch is OK for all Jews. Sephardic Jews are OK with rice. Ashkenazic Jews use lots of matzah meal. Coarsely ground meal for some purposes, cake meal (finely ground) for other purposes. And, of course, whole matzah or coarsely crumbled matzah farfel have an important place. Matzah lazagne can be made, substituting matzah for flat noodles between layers (put the matzah in dry, and of course, make it vegetarian because meat cannot be included in foods meals that include any dairy products). Fried matzah is like french toast, but made with broken matzah and egg. Some people make it savory, with onions, others serve it with maple syrup. Both are good.
