In a large mixing bowl, combine the sausage, shredded cheddar cheese, Bisquick, milk, and garlic powder. I recommend using your hands here, since it’s the easiest way to get everything mixed together well. The dough will be thick and a little sticky, but that’s totally fine. If you find the mixture’s a little too sticky, you can add a touch more Bisquick until it’s workable. Just make sure it’s not too dry; you want that perfect texture that holds together but isn’t too stiff.
