To make meatballs:
Pulse oats in a food processor until finely ground.
Squeeze the moisture out of the spinach by twisting in a clean towel- then chop.
Combine turkey, egg, oats, feta, sun-dried tomato, spinach, and salt until all ingredients are evenly distributed.
Portion into 20 evenly sized balls, place on a greased sheet tray and cook in pre-heated 350* oven for 10-15 minutes, until internal temperature reaches 165*.
Meanwhile, in a heavy bottom sauce pot, sautée garlic in olive oil until fragrant but not brown, about 1 minute.
Add crushed tomatoes and whole peeled tomatoes (crushing the whole peeled tomatoes with your hands as they go into the pot) and simmer for at least one hour.
Add basil and season to taste.
Add meatballs and simmer for 5 minutes or so.
Serve over pasta or zucchini noodles.
