Start by caramelizing your onions. Add 1 tbsp of olive oil to a sauté pan over medium heat. Toss in your diced onions and let them cook, stirring often, until they become soft and turn a light golden brown (about 5 minutes). Add the brown sugar and balsamic vinegar and stir to combine, letting the onions become coated with the mixture. Cook for an addition 1 to 2 minutes then remove from heat and let cool completely.
To prepare the hummus combine the garbonzo beans, tahini, garlic, lemon juice and sea salt in your food processor. Turn it on and slowly stream in the olive oil through the top chute until the mixture is smooth and creamy. Add more olive oil if desired. Add 1 to 2 tbsp of the cooled caramelized onions to the hummus and pulse just a few times to incorporate. Place the hummus in a serving dish and top with the remaining caramelized onions. Enjoy with pita chips or fresh cut veggies!
