It is important that the meatballs reach an internal temperature of 160 degrees, so be sure to prepare the meatballs according to package directions. Heat them in the microwave first. Place twenty meatballs in a microwave safe bowl, add two tablespoons of water and heat for 4 1/2 minutes.
Preheat the oven to 450 degrees.
Flatten the refrigerator biscuits, dry a meatball off with a paper towel, place a meatball in the center of the biscuit and wrap the dough around it, pinching the edges closed.
Once all of the meatballs are wrapped in dough, dip them into a mixture of warm water and baking soda.
Place them on a baking sheet lined with a silicone mat or parchment paper. Sprinkle with coarse salt.
Bake at 450 degrees for 7-10 minutes.
Brush with melted butter and sprinkle with additional coarse salt, if necessary.
Serve immediately, preferably with some warm, melted cheese like queso blanco.
