Add the carrot, onion and celery, season with salt and pepper and cook over moderately low heat, stirring, until the vegetables are very tender and caramelized, 20 minutes. Add the anchovies and tomato paste and cook, stirring, until the anchovies dissolve and the tomato paste is deep red, 5 minutes.

- Meanwhile, Make the Meatballs In a large bowl, combine the beef, ricotta, Parmigiano, egg, lemon zest, crushed red pepper, parsley, fennel, kosher salt and black pepper. Squeeze any excess milk from the bread and add the bread to the bowl. Mix the meat mixture well, then roll it into eighteen 1 1/2-inch balls; transfer to a baking sheet.
- Meanwhile, Make the Meatballs In a cast-iron skillet, heat 2 tablespoons of the canola oil. Cook half of the meatballs over moderate heat, turning, until golden brown and no longer pink within, about 15 minutes. Repeat with the remaining 2 tablespoons of canola oil and meatballs.

The uncooked meatballs can be refrigerated overnight. The cooked greens can be refrigerated for up to 2 days.
