Preheat the oven to 450degreesF. Drizzle the olive oil into a 9 x 13- inch baking dish and use your hand to evenly coat the entire surface. Set aside. Combine the ground pork, salt, cherry peppers, pickling liquid, bread, and eggs in a large mixing bowl and mix by hand until thoroughly incorporated.
Roll the mixture into round, golf ball-size meatballs (about 11/2 inches), making sure to pack the meat firmly. Place the balls in the prepared baking dish, being careful to line them up snugly and in even rows vertically and horizontally to form a grid. The meatballs should be touching one another.
Roast for 20 minutes, or until the meatballs are firm and cooked through. A meat thermometer inserted into the center of a meatball should read 165degreesF. Allow the meatballs to cool for 5 minutes in the baking dish before serving.
