Preheat oven to 400 degrees; grease 9x9 baking pan with olive oil. Place quinoa, garlic, parsley and eggs in food processor and process until almost smooth. Pour into a mixing bowl and mix well with ground meats, 3/4 cup Parmesan cheese, thyme, oregano, salt and pepper. Form into large meatballs, about 2 1/2 inches in diameter. Place in oiled baking dish and roast for 25 minutes or until just cooked through. Drain off excess cooking liquid. Spoon marinara sauce on top and bake until sauce is hot, about 5-10 minutes. Sprinkle with more Parmesan cheese and chopped parsley.
