Add all ingredients to a medium sized sauce pan and heat over medium heat, whisking to combine. Heat just until dates are softened, approximately 10 minutes.
Transfer sauce to a blender, or use an immersion blender to blend until smooth. Transfer sauce to an airtight container such as a mason jar and allow to cool. Refrigerate for up to two weeks.
Grilled Chicken
Combine the avocado oil and coconut milk in a ziplock bag. Season both sides of the chicken with salt and pepper and place in the bag with the marinade. Store in the fridge for 30 minutes or up to 6 hours.
Prepare one side of your grill for high, direct heat.
Make drainage holes in a sheet of aluminum foil with a grilling fork. Place foil sheet on grill grate. Place chicken on foil, baste both sides with BBQ sauce and cook, flipping once and basting with remaining sauce until cooked through, about 10-12 minutes on each side. Serve immediately, garnish with parsley or chives if desired.
Notes
For a thinner sauce, add 1 -2 tbsp of water after blending.
