1. Preheat the oven to 375° F and grease a 9- or 10-inch baking dish.

2. Whisk the eggs together in a large bowl. Add all remaining ingredients and stir until well combined. If using green onions, stir into the mixture and then pour into the prepared baking dish. 

3. Sprinkle with sesame seeds, if using, and place in the oven to bake for 35-45 minutes, or until golden on top and a toothpick inserted into the middle comes out clean. Let cool for a few minutes before serving.
