What on earth...
Of course it is!
It's a vegetable. EAT IT!
Use it how ever you like.
Google up some recipes... convert them to "Primal" if they have non-Primal ingredients.
Many people use it as a noodle replacement with traditional red meat sauce, just like spaghetti.
Or with a creamy white sauce and some other vegetables for a prima vera.
Or just add some butter and garlic and use it as a side dish.
Enjoy your food.
