Preheat oven to 300F. Add spinach to a bowl. Microwave at 30 sec intervals until the spinach is thawed. Squeeze all the water off the spinach. We don’t want any extra liquid!
Drain the artichoke hearts and chop into bite sized pieces. Mince the shallot and garlic.
Add the green yogurt, cottage cheese, mozzarella, parmesan, artichoke hearts, spinach, shallots, garlic, salt, pepper, and red pepper flakes to a bowl. Mix until well combined.
Transfer the mixture to a greased oven safe dish. Top with a handful of extra mozzarella (optional).
Cook in the oven for 15-20 min, until mixture is heated through and cheese starts to brown. Enjoy while it’s hot with crackers, chips, or veggies!
