Spray a medium sized casserole dish with non-stick cooking spray.
Place rolls on the bottom. You don't have to use the crescent rolls (I just happened to have some the first time and it stuck). Feel free to use any type of bread - leftover, dry stale bread works the best. You can cut it up, tear it, whatever suits your mood.
Layer the vegetables, ham, parsley, and cheese on top of the bread. Pour in the Egg substitute. You may need to press a bit to ensure all ingredients are covered with the egg.
If you aren't in a hurry, this recipe works better if you allow it to sit in the refrigerator (covered) for an hour (or up to overnight). This lets the flavors incorporate and the egg soak into the bread.
Cover with foil and bake in a 375 degree oven for 45 minutes. Uncover and finish for another 5-10. Ensure that the egg is set. If you choose to use a real-egg custard, you will not need to bake as long.
Cool, cut into squares, and serve. I like to serve it with a little of my favorite sauce or a few slices of fresh roasted green chilis (which I always have around).
Next time I make it, I want to use some fresh Ricotta cheese in the casserole -- let me know if you do and how it turns out.
Also - this makes a great leftover lunch!
