Caramelized onion spinach dip

from bake your day

ingredients:

for the caramelized onions:
3 tsp. olive oil
2 yellow onions, coarsely chopped
1 clove garlic, minced
1/4 tsp. salt
1-2 Tbs. water

for the dip:
16 ounces plain Greek yogurt (or sour cream)
1/4 cup mayonnaise, optional
10 ounces frozen chopped spinach, thawed and drained of excess water
1 can water chestnuts, chopped
1 package of vegetable dip mix (I like Knorr)
1/2 cup parmesan cheese, freshly shredded
1/4 cup shredded mozzarella cheese
1/8 tsp. cayenne pepper
1/2 tsp. black pepper
1/4 tsp. salt

directions:

To caramelize the onions: heat the oil in a large non-stick skillet over medium-high heat. Add the onions, garlic and salt and stir to combine. Cook for about 10 minutes on medium high until the onions are soft and very fragrant. Add the water, stir to combine. Reduce the heat to medium and cook for another 10 minutes, stirring often, with a lid on the pan, but left slightly ajar. After another 10 minutes, the onions should be brown and very fragrant.
While the onions cook, mix the Greek yogurt, mayonnaise, spinach, water chestnuts, dip mix, cheeses, cayenne pepper, black pepper and salt in a large bowl. Set aside.
When the onions are caramelized, add them to the Greek yogurt mixture and stir well to combine. Cover and refrigerate for at least 30 minutes. Serve chilled with chips, crackers, pita bread or veggies.
