Drain cashews then add to food processor with lemon, oil and salt. Blend until smooth.
Next add in remaining ingredients and continue to blend until mixed through.
You may need to do a taste test and add additional salt or lemon juice if desired.
If you want to add flavorings, you can do that now. Just transfer the cashew mixture to a bowl and stir in your add-on's.
Serve immediately or store in a glass container in the refrigerator for up to 7 days or in the freezer for later use.
