Melt oil in a non-stick pan. Add the salt, onion and garlic. I used the oil from the sun dried tomato jar.
Allow the onions to cook over medium to low heat for approximately 25 minutes, stirring occasionally until caramelized.
Cook the pasta in a separate pot according to package directions, reserving at least 1 ½ cups of pasta water.
Add the thyme, sun dried tomatoes and white wine and deglaze the pan. Pour in the pasta water and cashew cream until a creamy sauce is formed, and then add the pasta to the pan. Mix in a handful of spinach or basil to serve. Enjoy immediately with salt and pepper!
