Bag-cooked omelettes turning gray when stored in the fridge
So, we found the omelette in a bag recipe, and decided to use it. Pretty simple, beat the eggs, drop in ingredients, (Usually either Great Value Mozzarella, Fiesta Blend Cheese, or Cheddar) and some Jimmy Dean's Breakfast sausage, boil for 20mins, done.
We store them in the fridge since we don't have time in the mornings, and eat them throughout the week. They're perfect for my father who eats them at work (microwaves them, about a minute or so) and for me if I'm looking for quick meal.
Problem is, that at times they turn a grayish color, as they're put onto the plate and break up the omelette, you can see grayish/black spots.
Are we storing them wrong? Are they safe to eat? Any suggestions would be helpful.

Cooking, not storage, to blame
Storing cooked eggs under refrigeration for a week is not turning your eggs gray. Instead the discoloration is from the iron in the yolk reacting with the sulfur in the albumen at temperatures of 170F or higher creating ferrous sulfide.
Overcooking the omelettes initially, or perhaps hot spots from the reheating method, create the gray-green discoloration. While unappetizing, the discoloration is not harmful.

Why did my omelette turned GREY?
The gray layer is caused by a reaction between the iron in the egg yolks and sulfur in the whites. When the eggs are cooked too long or at too high a temperature, they form a drab compound called "ferrous sulfide." You might also notice a distinct sulfury odor when you peel the eggs.How long will cooked omelettes last in the fridge?
It is safe to keep your omelet in the fridge in an airtight container for about 3-4 days. When storing them in the refrigerator, be sure to store them in a tight container or airtight bag. Ziplock bags are great for storing omelets. You can even freeze your omelet for up to 4 months.Can you Refrigerate cooked omelettes?
Store omelets in the fridge for only about 3-4 days. Omelets should be tightly wrapped or sealed in an airtight container or bag. The key to storing them is to make sure they are sealed tightly into whatever storage format you use.Why do my cooked eggs look GREY?
This process happens at 77\xb0C for ovalbumin. But above 70\xb0C, the sulphur also forms hydrogen sulphide that reacts with iron in the egg yolk to form iron sulphide, and this gives it a greenish grey colour. You can prevent this by running the eggs under the cold tap to lower their temperature as soon as they are cooked.More answers regarding bag-cooked omelettes turning gray when stored in the fridge
Answer 2
Try storing them in the freezer. You can cook them at home in boiling water (straight from the freezer) like you do with the refrigerated ones. Or, you can take them to work and cook them in the microwave when you get there. (note: they will thaw out on the way to work)
