Mason Jar Omelet

Meal Prep Made
Mason Jar Omelets taste just like their traditional cousins. Just get over the fact that they just don't look as beautiful as a pan omelet. Mason Jar Omelets are the easiest way to have a hearty egg breakfast without all the mess of cleaning up a pan. We always add in leftover cooked peppers and onions, however any cooked veggies you have on hand can work. At 1.14 per serving you are slaying your food budget.

We used store bought eggs to calculate the costs at an average of 2.49 a dozen for organic. You can lower the cost with budget store bought eggs at .99 per dozen. Most farmers market eggs will cost approximately $5.00 per dozen. However eggs that are pasture-raised can contain more nutritional value. Know what your goals are when deciding what ingredients to purchase for your meals. 
We did not add salt or pepper to this recipe. If you like you can add in salt pepper or even a bit of cayenne pepper to spice it up. 
Feel free to add a bit of your favorite cheese to add some more flavor. You can even change up the vegetables in the dish to include mushroom or exclude the spinach.  If you like you can add some cheese, please note that changing up the ingredients will change the cost per serving and nutritional values including calories.
Your Mason Jar Omelet can be eaten directly our of the jar, the jars travel well inside your lunch bag.
Be sure to store the bag in the refrigerator as eggs must be kept cool. 
Never microwave a Mason jar for more than 5 minutes
