These Low Calorie Pesto Chicken Pita Sandwich are just 413 calories each and packed with 45.6g of protein. You can swap out the whole wheat pitas for low carb pitas, but I wanted to use the easiest to find for the nutrition. Special Tip: If you are making these for just one person, simply cook the chicken and bell peppers and put 1/2 in a covered container and place in the fridge. Then all you need to do is assemble the sandwich tomorrow or the next day for lunch or dinner. They are great hot or cold!
