Preheat the oven to 350 °F (175 °C).
Take a 10-inch (25 cm) pie pan and grease it generously with butter.
Spread the broccoli, bell pepper and chicken evenly in the greased pie pan.
Add the eggs, heavy cream, and the shredded cheese to a medium bowl, plus the salt and pepper (or other spices) if using. Mix until well combined.
Pour the egg mixture evenly over the broccoli and the chicken.
Bake in the preheated oven for 40 minutes, or until the filling is set and the cheese is melted and golden brown.
Remove from the oven. Let set for 15 minutes, the slice and serve.
