Peel and slice onions very thinly
Melt butter in a medium saucepan or dutch oven. Add onions, salt, and coconut sugar. Mix well. Sauté 10-15 minutes over medium heat, stir frequently. Stir in splash of wine or broth to deglaze pan. Let sizzle out. Repeat. After about 30 minutes onions should be done.
In a large high powered blender, blend cashews, lemon juice, apple cider vinegar, salt, optional Worcestershire sauce and water. Start with 1/4 cup of water and add up to 1/2 cup (total) if needed. Less water with result in thicker consistency but add more if your blender needs it to blend smoothly.
Pour into a bowl. Mix in most of the cooled onions. Top with parsley, chives, garlic chips and reserved onions. Chill 1-2 hours for thicker texture and more flavor. Enjoy!
