Preheat the oven to 425 degrees, and grease a 12-cup muffin tin.
In a large bowl, combine the flour, baking powder, sea salt, and seasonings.
In a separate bowl, combine the plant milk, olive oil, and flaxseed. Let the flaxseed mixture sit while you finely chop the kale and chives.
Pour the wet ingredients into the dry ingredients, stir to combine.
Stir in the kale and chives until they are thoroughly incorporated into the batter.
Use an ice cream scoop to evenly fill the greased muffin tin.
Bake for 20 minutes or until the tops are golden brown. Cool for about 10 minutes before serving. Enjoy!
