These are perfect little savory bites for an appetizer table or, if you make them a little bigger, to have with soup. Different herbs will yield different flavors, so be creative with your mix! For this example, I used fresh basil, rosemary and oregano out of my garden. Dried herbs would also be great.
Preheat oven to 425 degrees. Sift flour, baking powder and salt into a bowl. Cut butter into small cubes. Use a pastry cutter to mix into the flour until the butter is in small crumb-size pieces.
Add the pepperoni, onion, herbs and cheese. Mix with a fork to cover with the flour. Pour in the milk and using a spatula, fold the milk into the flour, bringing the flour up from the bottom and into the milk just until incorporated.
Place the dough onto a well-floured surface. Using your fingers, press the dough out until it is a little less than 1". Use a 2" biscuit cutter and push straight down onto the dough - don't twist - and pull straight up. The edges of the scones should look "rough" - these layers are what will separate to give you the puff.
Spray a cookie sheet with non-stick spray. Transfer scones to the cookie sheet. Brush with milk. Re-roll dough, press out and cut until all dough is used. Bake until the scones are nicely browned - my oven took 15 minutes. If you opt for a larger sized biscuit cutter, adjust to a longer baking time. Serve warm or at room temperature.
