In a large saucepan bring the vegetable broth and cashewmilk to a boil.
Once the liquid is boiling add in the salt and quick cooking polenta. Whisk the polenta constantly for about 5 minutes or until it is thick and the liquid is absorbed. Whisk in the dried basil, garlic powder, and black pepper.
Spray a quarter sheet pan or 9x13 baking pan with cooking spray then pour in the polenta, smoothing it into an even single layer.
Cover the polenta and refrigerate until it is firm, at least an hour or up to overnight.When the polenta is firm, preheat your oven to 450° F.
Line a half baking sheet with parchment paper. Cut the polenta into fry shapes (about 1/2-3/4 inch in width) then place each fry on the parchment lined baking sheet. Spray or brush the fries with olive oil and sprinkle with salt.
Place the fries on the middle rack of the oven and bake for 15 minutes. Remove from the oven and flip over to the other side and bake for another 10-15 minutes or until they are golden and crisp.
Serve with the spicy marinara sauce.
