Bring a pot of salted water to a boil, add the pasta, and cook according to the package directions.
While the pasta is cooking, heat a tablespoon of extra virgin olive oil in a pan, add the chopped onion and minced garlic until golden. Add the tomato sauce and season well with salt and pepper.
After 5 minutes, add the finely chopped basil, rosemary, parsley, and thyme. Let the sauce cook for another 5 minutes to infuse it with the herbs' aromatic flavors.
Add the cashew cream (store-bought or see below for instructions) and combine well. Add the cooked pasta and toss well for about 2-3 minutes on low heat to allow the pasta to absorb the sauce.
Serve hot, and garnish with some fresh thyme or basil leaves and enjoy.
