I had a few friends over and looked in my fridge to decide what to prepare.
In my fridge, I had delicious low-carb pita bread, spinach, shredded cheese, shiitake mushrooms, white button mushrooms, onions, and egg whites.
After looking through my recipe book, where I keep print-outs of all previously used recipes, I came across my favorite quiche recipe. If you want a hearty, quick, and easy recipe, go for quiche. You can combine almost anything with eggs and make a great quiche. Since I needed to be really fast and didn't have time to return to the store, I used this pita bread to make it.
