For the cauliflower gnocchi:
Place the cauliflower florets in a food processor and pulse until it looks a little like rice.
Spoon the cauliflower into a microwave safe bowl and microwave for 5 minutes.
Once microwaved, spread the cauliflower on a towel to cool.
When the cauliflower has cooled completely, wrap it in a towel and squeeze the water out. It's okay if there's a little moisture left as long as you squeeze out most of it.
Place the cauliflower into the food processor and pulse it again until smooth. Then, gradually add in the flour.
Add the garlic powder, Mazola Corn Oil, and water, and continue pulsing until a dough forms. Then, turn the dough out onto a floured surface.
Break off small pieces of dough and shape them into little balls. Using the back of a fork, roll dough down the prongs to form gnocchi.
To cook the gnocchi: bring a pot of salted water to a boil and carefully add the gnocchi. Cook until the gnocchi float to the top (it'll only take a few minutes) and remove with a slotted spoon.
For the marinara sauce:
Heat the Mazola Corn Oil over medium heat.
Add the garlic and onion and cook, stirring consistently, until the onion has softened and the garlic is fragrant.
Carefully pour in the can of crushed tomatoes.
Add the Italian seasoning and salt and pepper. Stir.
Bring sauce to a boil, then turn down the heat, letting the sauce simmer.
The longer the sauce cooks, the better it will be, but cook until it has thickened up a bit, 10-15 minutes.
Serve with gnocchi, crushed red pepper, shaved Parmesan, and fresh basil, if desired.
