Salt, pepper, and a dash of cayenne (or chili powder for less heat)
Thaw spinach & squeeze out water, combine all ingredients and mix well. Transfer to a small baking dish (spray with olive oil or coconut oil cooking spray) and bake for 25-30 minutes at 350, until dip is bubbling and the cheese is starting to brown around the edges. Serve with veggies and/or organic blue chips.
