Squirt Papa John's Garlic Sauce into an ice cube tray and freeze for two hours or until frozen through.
Set up a dredging station with three bowls — flour in the first one, beaten eggs and milk in the second one and breadcrumbs in the third one.
Pop out the Papa John's Garlic Sauce cubes and coat each one in flour, submerge it in egg wash and cover it in breadcrumbs. Repeat this step a second time if necessary.
Place the breaded cubes back in your freezer for another hour or until frozen through.
Heat oil in deep fryer or heavy skillet to 375°F.
Fry the breaded cubes in batches for 30 - 45 seconds or until golden brown and cooked through and then cool on paper towels.
Serve with pizza sauce or even more Papa John's Garlic Sauce for dipping.
