Cook the potatoes:

• Boil cut potatoes in salted boiling water until they easily fall from a knife pierced into them. Allow to cool, then dice and place in a large bowl.

Cook the eggs:

• Bring a medium pot of water to a boil (large enough to accommodate all the eggs in a single layer). As soon as the water boils, gently add the eggs. Set a timer for 9 minutes. Bring back to a boil and then turn down to a simmer. Meanwhile set up a bowl of ice water, large enough to accommodate all the eggs. When the eggs are done, use a slotted spoon to immediately transfer the eggs to the bowl of ice water. Peel and chop when cool enough to handle.

Cook the macaroni:

• Bring a large pot of water to a boil. Add salt. Cook macaroni according to package instructions, drain, then rinse with cold water and set aside.

Make the sauce:

• In a small bowl mix together the sauce ingredients. Add the onion, eggs, carrots, peas, and macaroni to the bowl with the potatoes. Mix in dressing until thoroughly combined. Check seasonings.

• Preheat the oven to 450° F. Grease a 9×13 inch baking dish with olive oil.
• Take the bread and run it under water until dampened but not soaked. Gently squeeze the excess water out of the bread and then crumble the dampened bread into pieces.
• In a bowl, combine the sausage, chicken, bread crumble, eggs, shallots, garlic, pepperoncinis, and a pinch each of salt and pepper. Coat your hands with olive oil, then roll the meat into balls (about 2 tablespoons meat per ball), and place them into the prepared baking dish. Bake for 15 minutes or until the meatballs are crisp on the outside, but not yet cooked through on the inside.
• Remove from the oven and pour the marinara over top the meatballs. Cover the pan with foil and bake for 15 minutes longer, or until the meatballs are cooked through. Remove the foil and add the cheeses and oregano. Bake until the cheese is melted and golden, about 10 minutes. Serve topped with fresh oregano.
