Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.

Cut the pizza dough into 14 equal pieces and roll each piece into 8-inch strips.

Place a piece of American cheese and a thawed mini meatball at one end of the dough strip, then tightly roll it up and seal the seams.

In a large pot, bring about 4 cups of water to a gentle boil and stir in ¼ cup of baking soda until dissolved. Boil each bomb for 20-30 seconds.

Remove the bombs with a slotted spoon, place on the baking sheet, and brush with beaten egg. Sprinkle with coarse sea salt.

Bake for 15-20 minutes until golden brown.

Let cool slightly and serve warm with yellow mustard for dipping.
