Preheat oven 450 degrees Fahrenheit and spray 8 inch baking dish with cooking spray. Prepare pasta as directed on box for al dente.
Mix panko, paprika and olive oil and set aside. Chop broccoli.
Heat milk in a medium saucepan over medium-high heat until steaming, stir in cheddar until melted. Take off heat and add yogurt, nutmeg, mustard, salt and pepper. Whisk together.
Drain pasta and add to the cheese sauce; mix well.(optional: Line baking dish with fresh spinach). Add broccoli to bottom of pan. Spread the pasta mixture on top of broccoli, then sprinkle with the panko mixture, and top off with parmesan cheese.
