Dice bell peppers and onions.
Brown ground beef in olive oil and season with Italian herbs, salt & pepper, careful not to overcook.

In large mixing bowl, combine meat, veggies, pasta and marinara sauce, reserve some sauce to make adjustments for right amount. Pasta will soak up some sauce while baking, so be generous with sauce.
Drizzle olive oil in bottom of Dutch Oven or baking dish. Pour above mixture into baking dish, top with mozzarella (1 cup per Dutch oven). If using a real Dutch Oven, rub olive oil on lid so cheese does not stick when cooking.
If cooking in conventional oven, cover dish so lid is not touching cheese, cook until bubbly, usually 35 min to 1 hour. Remove lid and broil until cheese is browned (don't walk away).
Let rest for 15 min, sprinkle with parsley for color.
