Mix all the ground meat(s) and seasonings until well combined. I find it best to use my hands. Cook a small piece to test the seasonings. Adjust if needed. Set in the fridge for a couple hours or overnight if desired.
When ready to make the biscuits, preheat the oven to 350°F/180°C
Make the biscuit mix by measuring the flour, baking powder, salt and butter into your largest mixing bowl.
Use a pastry cutter, two knives or your fingers to mix the butter into the other ingredients. I use my fingers to pinch the butter into the dry ingredients. It will resemble fine crumbs or corn meal when mixed.
Mix in the yogurt (if using), cheese and sausage and blend well. It's easiest to use your hands and it may take awhile to get everything mixed together. The dough will be very stiff but should be well mixed.
Form into one inch balls (about golf ball sized) and place on a greased baking sheet. Leave some space between each one. Flatten slightly if desired.
Bake for 17 to 20 minutes, turning the tray at the 10 minute mark. The bottoms should be golden brown, while the interior should be cooked all the way through. If not, increase the cooking time slightly and make note for future batches.
