Preheat your oven to 375°F (190°C) and prepare a baking sheet lined with parchment paper or a greased muffin tin.

In a large mixing bowl, combine 1 cup of plain 2% Greek yogurt with 2 large eggs. Whisk until smooth and creamy.

In another bowl, whisk together 2 cups of all-purpose flour, ¼ cup of ground flaxseed, 1 tablespoon of baking powder, ½ teaspoon of salt, 1 teaspoon of garlic powder, and optional red pepper flakes.

Carefully add the dry mixture into the wet yogurt and egg mixture, and gently stir until just combined.

Fold in your choice of mix-ins such as ham and cheese chive or Mediterranean sausage with sun-dried tomatoes and feta.

Using a ⅓ cup scoop, portion out the biscuit dough onto the prepared baking sheet, leaving space between each.

Sprinkle reserved cheese on top of each biscuit and bake for approximately 25 minutes until golden brown.

Allow the biscuits to cool for at least 10 minutes before serving.
