1 Tsp Cayenne Pepper

Instructions

Strip the kale from its stem

Add in the cream mixture and let simmer for 2-3 minutes stirring often
Add in 3/4 of the parmesan cheese reserving 1/4 for the top
Place the greens in a casserole dish open and release them from their squeezed state, no one wants to eat a wadded ball of greens
Pour the creamy mixture over the greens and stir with a wooden spoon or rubber spatula so you don't scratch your casserole dish

Bake covered for 30 minutes then uncover for another 10 -15 minutes until brown on top
