    My family loved this casserole. They left no leftovers. Will make many more times. Very easy, very good.

    I find this idea to be brilliant for times if ever I have ended up not having time to cook dinner after work, I came across this five days back and I very much am thankful to you for sharing your idea on here.

    1. You could do that with any egg mixture/omelette setup. Just make sure to cover it properly b4 refrigeration. Maybe give it a quick stir/whisk before putting it in the oven.
      You could keep it in the fridge for a few days if you need to.

    I have made this ahead of time and placed it into a ziplock and frozen until I needed it. I placed in the fridge the night ahead of time to defrost and into the oven the next morning… worked beautifully.

    I’m sure it’s a little more expensive and maybe not quite as good, but this makes a good “go to in a hurry” meal if you use frozen Potatoes O’Brien instead of preparing the real potatoes, onion and bell pepper. I know it is better to cook from scratch, but if I keep the Potatoes O’Brien, cheese and ham in the freezer (I always buy hams at holidays and either freeze or can much of the meat), with the help of my chickens, it is on hand for anyone to easily put together if I have company for dinner or for breakfast or if I am ill.

    1. We generally have all these things on hand, but using frozen onion & peppers blend/ pepper stir fry, frozen hashbrowns or potatoes o’Brien from the refrigerated case would definitely reduce the preparation time
      .
      This dish will be perfect as a breakfast for dinner on a busy night.
      Could stand alone or be served with a simple salad, fresh fruit, grits, warm honeybutter biscuits or a slice of toast

  5. I am always looking for breakfast casseroles for company and the holidays. This one is definitely a keeper!
