In a jar with a lid mix the olive oil, avocado oil, apple cider vinegar, garlic clove, teaspoonfuls mustard and salt and pepper. Cover and mix until everything is integrated. Add hazelnuts and serve over your favorite greens or salad.
Notes
If you are using raw hazelnuts, roast them in a saucepan over medium heat until they begin to brown, about 5 to 7 minutes constantly moving, they burn very fast. When they are ready, put them on a clean cloth to peel them. Roughly chop and set aside.
