Heat oven to 400ºF. Place chicken bites on a baking sheet and cook for 15 minutes, until hot. Remove from the oven and set aside.
While chicken heats, cut 4½-inch circles from each flour tortilla and nestle each into a cup of a greased muffin tin, pleating the edges to fit it into the cup.
To each tortilla cup add 1 tablespoon mozzarella and 2 tablespoons marinara sauce. When chicken is hot, nestle one bite into each cup. Sprinkle each with ½ tablespoon Parmesan and an extra sprinkle of mozzarella if desired.
Bake chicken Parmesan cups until cheese is melted and sauce is bubbly, about 18 minutes. Let cool slightly, garnish with chopped parsley if desired, and serve hot.
