Preheat the oven to 425F. Place a piece of parchment paper over a large baking sheet and set aside.
In a high powdered blender combine the biscuit ingredients; oats, eggs, hemp milk, butter, baking powder, and sea salt. Blend on high for 2 minutes.
Using a 1 1/2 tablespoon cookie scoop, transfer the batter to the prepared cookie sheet. Bake for 10-12 minutes. Remove from the oven and let cool on a wire rack.
Preheat a large cast iron skillet over medium-high heat on the stove top. Add the pork sausage and use a wooden spoon to crumbled the pork. Stir every couple minutes until the pork has cooked through.
Working quickly add the hemp milk, buckwheat flour, and sea salt. Use a whisk to combine and let simmer until the mixture thickens into a gravy. Remove from heat and serve over the egg biscuits.
