Put ricotta in a colander and let drain for 30 minutes.
Wash herbs and boil in unsalted water for 20 minutes. Turn off, drain, let cool, squeeze the herbs, and finely chop with a knife.
In a bowl, mash the ricotta with a fork.
Gather ricotta, herbs, bread crumbs, Parmesan, a pinch of salt, and the egg in a bowl. Mix first with a fork and then with your hands.
Let the meatball dough rest for 10 minutes in the refrigerator.
Form equal-sized meatballs using a spoon to help with the quantity. I make about 20.
Lay the meatballs in the sauce and cook uncovered on a medium-low stove for ten minutes. Halfway through cooking, gently turn them over.
Turn off the heat and let rest a few minutes, uncovered, before serving.
You can prepare them the day before and store them in the refrigerator.
Keep any leftovers in the refrigerator for a few days.
