Knife and cutting board

non-stick cooking spray

Ingredients

7 large onions diced
¼ cup olive oil
¾ cup pure maple syrup
¼ cup apple cider vinegar
¼ cup balsamic vinegar

Instructions

start by caramelizing and dicing onions. You can caramelize on a cooktop or in your slow cooker.* I prefer to use my slow cooker and let it cook on its own overnight.
7 large onions, ¼ cup olive oil
add remaining ingredients to slow cooker and cook on low with the lid off for 2-3 hours until onions and liquid become thick.
¾ cup pure maple syrup, ¼ cup apple cider vinegar, ¼ cup balsamic vinegar, 1½ teaspoon salt, 1 teaspoon ground cinnamon
use an immersion blender to fully blend all ingredients
Allow to cool and enjoy
