Batch cooking simply means that you take a few hours to do lots of cooking for the week. Then you're simply re-heating the leftovers for the next four to five days. I usually suggest two batch days per week. Once you get in the habit of taking the time to do this each week, you will save yourself tons of frustration over having nothing healthy to eat in a pinch.
The biggest problem my clients come across is failing to prepare. They are left rushing around with nothing to eat which means they resort to grabbing anything that's quick and easy. We all know quick and easy means convenience foods. Inevitably, this is when things start going down hill. A few days of that stuff and they are NOT happy with their weight loss progress and/or the way they feel.
That's where this Frittata comes in. No more frustration in the morning over what to eat. It's a very simple dish that only needs to be made every 4 days. Changing up the veggies and seasonings will give you a whole new dish each time. You can also add ground meat or sausage to the pan before heating the veggies. I usually have a serving of home made sausage on the side.
