In a medium sized saucepan over high heat, add all ingredients through the black pepper. Do not add the softer vegetables, zucchini and spinach, at this time. Bring ingredients to a boil and reduce heat to a simmer. Partially cover and cook for 20 minutes.
Add zucchini and spinach, stir, and cook for another 10 minutes partially covered.
Test farro for doneness. Farro is a crunchier and nutty grain. Sprinkle with parsley and enjoy!
