Drape one Joseph’s pita across the bottom of a personal sized casserole dish (mine is about 5x7), or double or triple this recipe in a larger, normal sized pan.
In a mixing bowl, whisk together egg whites, whole egg, veggies, chilis, chopped Canadian bacon, seasonings, and parmesan. Pour over pita in casserole dish. You can either cover overnight like I did and bake in the morning, or bake immediately - either way at 350 for 45-50 minutes uncovered until set in the middle. If you use a larger pan and it's shallow, keep an eye on it after 30 minutes.
If you count macros, you can log this directly from MFP under "Lillie Eats and Tells Egg White Veggie Breakfast Bake". Typically I provide serving sizes in grams but I only made this the once, and didn't plan to share (remember I thought it'd be gross), which means I don't have the final weight! So for this one, a serving is half of this small pan. If you double it, you'll know a serving is 1/4th.
