Whisk together the dry ingredients, then whisk in the milk and egg. Fold in the cheese, prosciutto, basil, red pepper and garlic and let stand for ten minutes.
While you wait, preheat the oven to 375-degees while you grease a mini-muffin tin.
Scoop the batter into the tin (I like using my 1" cookie scoop for this). Bake for about 22 minutes until the puffs are golen brown.
Serve hot with the tomato sauce for dipping.
Notes
I found that these freeze (double-bagged) and reheat wonderfully, so they would be great to make before a party. I felt like the red pepper was a little overpowering and I'd leave it out next time (Rachel Ray's recipe actually has you serve the red peppers along side the puffs, perhaps for this reason!)
