Preheat the oven to 400?F and line a baking tray with parchment paper.

In a medium mixing bowl, whisk together Greek yogurt and eggs. In a separate medium mixing bowl, combine flour, ground flaxseed, garlic powder, red pepper flakes, baking powder, and salt.

Slowly add the dry ingredients into the wet ingredients, mixing well.

Add mix-ins including vegetables, herbs, and cooked meat along with 1 cup of the cheese and the ham. Mix until the ingredients are fully combined, using your hands to ensure everything is fully incorporated.

Lightly flour your hands and divide the dough into 12 even-sized 1-inch thick round disk-shaped biscuits (about ? cup of batter in each). Arrange the biscuits on the prepared baking tray.

Sprinkle the tops with the remaining cheese.

Bake at 400?F for 5 minutes, then decrease the temperature to 350?F and bake for an additional 20 minutes (do not open the oven in between).

Once the bottoms of the biscuits are golden brown and the tops are just beginning to brown, your biscuits are done!
