Begin by preheating your oven to 350ºF. Next, grease either a 1-quart casserole dish or an 8×8 glass pan and set it aside.
In a large mixing bowl, combine yogurt, chopped artichoke hearts, fresh spinach, garlic, crumbled feta, mozzarella, and shredded parmesan. Carefully fold all the ingredients together using a spatula until they are well-mixed.
Pour the mixture into the prepared baking dish, then generously sprinkle additional mozzarella and parmesan on top.
Bake for 40-45 minutes or until the cheese topping turns a lovely golden hue. Alternatively, you can switch the oven to broil during the last 5 minutes to achieve that golden cheese topping.
Take it out of the oven and allow it to rest for 10 minutes.
Pair it with your preferred vegan pita, chips, or crackers, and enjoy!
