Place your zucchini noodles in a collander and season with about 2 teaspoons salt. Allow to sit for 10 minutes while the salt draws out all the extra moisture.
Rinse your low carb noodles in water. I let mine soak in a bowl of fresh water for 10 minutes.
Heat your cast iron skillet over medium heat. Add the ghee and sliced sausages. Cook for 5 minutes, stirring occasionally, until the edges are crispy. Spoon out and transfer to a bowl.
In the same cooking fat, add the broccoli, bell pepper, red onion, kale and blackened seasoning. Cook for 5-8 minutes, until the veggies are soft. Turn off the heat.
Make the pasta sauce in your high speed blender. Add the bone broth, the cashews that have been soaking in the bone broth, and squeeze out the cloves from the head of roasted garlic. Blend on high for 1 minute until creamy and smooth.
Drain your low carb noodles from the water. Place your low carb noodles and salted zucchini noodles in a nut milk bag (or use a cheesecloth or kitchen towel). Squeeze firmly to remove all the extra moisture from the zucchini noodles and the low carb noodles. You will be surprised how much moisture comes out!
Transfer the zucchini noodles and low carb noodles to your cast iron skillet. Pour on the creamy garlic sauce. Allow it to warm gently from the residual heat from your cast iron skillet for 1 minute, stirring occasionally.
Serve warm. Leftovers will keep in an airtight container refrigerated for at least 1 week.
