Add collard greens, half of the curry powder (1 tsp as original recipe is written), coconut sugar, and a healthy pinch sea salt. Stir to combine and reduce heat slightly to medium-low. Cook for 4-5 minutes, stirring occasionally, or until greens appear tender but not mushy.
Add kale, another pinch of sea salt, remaining curry powder (1 tsp as original recipe is written), and the coconut milk. Stir to combine and cover once more to steam for 2-4 minutes, or until kale appears tender.
