Preheat the oven to 375℉.
Butter the bundt pan and sprinkle with bread crumbs. Shake the pan so that the bread crumbs stick to the butter.
Add half the mixture to the bottom of the pan. Make a ditch in the center for the filling.
Add a little bit of meat sauce, peas, meatballs, boiled eggs, and smoked scamorza. Add a little bit more meat sauce on top and then add the other half of the mixture on top. Flatten it out and sprinkle with bread crumbs. Spray the breadcrumbs with olive oil spray to get a nice golden crust.
Bake for 50-55 minutes.
Wait 30 minutes before trying to flip out of the pan. You have to give it an opportunity to set or it will fall apart when flipped.
If you have extra stuffing ingredients, you can mix them with sauce and add them to the center hole of the Sartù.
