Preheat oven to 350°F. In a large mixing bowl, whisk together the eggs.
Whisk in the mustard, garlic and herb seasoning, and heavy whipping cream.
When that’s blended well, slowly whisk in the tomato sauce until it’s no longer lumpy. Add in the diced chicken and broccoli florets.
Grease a casserole dish or a large baking pan then pour in the Italian bake.
Sprinkle Parmesan cheese and parsley flakes on top of the Italian bake. Bake for 30-40 minutes at 350°F, or until the top looks like a crust.
Before serving, top the Italian bake with some sharp extra sharp cheese. You could also use any other cheese that you like, such as mozzarella or pepper jack.
