Preheat oven to 400F.
In a large mixing bowl, whisk together oat flour, baking powder and salt.
In a separate bowl, whisk together the eggs, yogurt (or cottage cheese), and almond milk.
Next, gradually whisk the wet ingredients into the flour until well combined and smooth.
Heat the olive oil in a large sauté pan over medium heat. Add in the diced sausage and gently brown. After a few minutes add in the chopped spinach and green onions and sauté until wilted, about 5 more minutes. Remove the pan from the heat and let cool for about 5 minutes.
Fold the mixture into the egg batter.
In a silicone muffin mold, divide evenly into each cup, about 3/4 of the way full.
Bake for 25 minutes. Once cool enough to handle, pop muffins out of the silicone molds. Enjoy!
