This recipe is versatile and can be doubled if you want to make a larger serving. The fingerlings called for 24 oz , which is the whole bag of fingerlings. But as this recipe is for 2-3 people, that can be a lot of potatoes. You can save the remaining for breakfast or lunch the next day or only cook half of the bag.
If you don't have parmesan cheese, mozzarella is a good substitute.
Also if you like a little more sauce on the chicken, you can add 1 more tomato.
