User Manual Ninja NN310 Precision Processor™ with Auto-Spiralizer™

No. Spaghetti squash doesn't need to be soiralized. It has to be cooked, and then the strands are scooped out of the shell.

Perhaps if the cheese is very hard. I usually just use a grater if in doubt.

You just press the button once to turn on and then once to turn.

Yes it can but the container is small so you may have to do several batches depending on the size of dish you are making

You get two of the blades for the spiralizer. I suspect you could do hard cheese but may have to purchase the optional blades to do scalloped potatoes. Makes great Curley fries.

They can be ordered from Ninja directly, although you may not be able to find them on their website, I couldn’t. I called and ordered. But there is only one other disc, a slicer.

I’ve never made it with this machine but I could see it working.

Yes it does (grounded) use pulse if you want the meat in bigger pieces

Yes! Using the food processor bowl and blade, pulse several times to get the size you want.
