Preheat oven to 400F. Line a large baking pan with parchment paper.
In a large bowl, mix together the flour, garlic powder, salt, and baking powder. Add the softened butter and mix with your hands until crumb-like texture.
Add the yogurt and beaten eggs. Mix until almost all flour is absorbed.
Add the chopped spinach, herbs, shredded cheddar, and browned sausage. Mix until well-combined.
Use a large ice cream scooper or spoon to drop 12 evenly portioned biscuit-like shapes onto the prepared pan.
Bake at 400F for 6 minutes, then reduce heat to 350F for 15-20 minutes, until deeply golden.
