First, add cashews to a bowl and cover with boiling water for 25-30 minutes, or until the cashews are soft.
While the cashews are soaking prepare the spinach and kale; de-stem and chop the kale, then wash and dry the spinach (chop and remove stems if desired). When the cashews have about 5-10 minutes left, preheat the oven to 400 °F. Grease a baking dish (see notes) with avocado oil and set aside.
Drain and rinse the cashews and add the rest of the ingredients listed under "cashew cream" to the blender (water, lemon, garlic, tamari, salt, & pepper). Blend on high for 10-20 seconds, or until smooth.
Warm a large skillet on medium-low heat and add kale. Drizzle with avocado oil and a good sprinkle of salt, pepper, and garlic granules. Continuously stir, as it starts to decrease in size, add spinach to the pan and continue to stir until both greens are wilted *add more seasonings or oil as the greens cook if needed
Remove from heat and stir in the cashew cream and vegan parmesan cheese. Pour into the greased baking dish and top with hemp seeds, additional cheese, pepper, and crushed red pepper (pepper and crushed red pepper are optional).
Place on the middle rack in the oven and bake for 10-13 minutes or until the top is golden and the cheese has fully melted.
Remove from the oven and enjoy with tortilla chips, crackers, or veggies.
