Start boiling water for your rigatoni, cook according to package instructions.
While you are bringing water to a boil, drain the soaked cashews then add them, the vegetable broth, nutritional yeast and lemon juice to a blender. Blend on high until nice and smooth scraping down the sides as needed. It may take a few minutes. Now add salt and pepper to taste. Just leave in the blender for a few minutes until you need it.
Once the water is boiling, cook your pasta until it is al dente. Drain when finished.
In the mean time, heat the olive oil in a large skillet, on medium high. Add the garlic and saute for a minute. Then add the spinach and sun dried tomatoes. Season with a pinch of salt and pepper.
Cook for a few minutes until the spinach has wilted and the sun dried tomatoes are soft. Add the wine and simmer for about 5 minutes. Reduce heat as needed.
Now stir in the cashew cream sauce until completely combined. Taste and adjust seasoning adding more salt and pepper if needed.
Turn the heat off and add the rigatoni to the skillet. Toss the pasta in the sauce and coat completely. Serve immediately! I topped mine with fresh basil and cracked black pepper!
