This is from America's Test Kitchen's book all about Pasta. I used Pepper Jack cheese instead of the Monterrey Jack and it was yummy. The meal gets a little heat from the Chipotle pepper so if you're not a fan of heat, use the cheese called for. Chipotle peppers are sold in a can in the Mexican aisle of most grocery stores. You only need one pepper/chile for this recipe so line a cookie sheet with waxed paper and spread out the rest of the peppers on it and freeze them. When they're frozen, put them in a ziploc bag and you'll have a chipotle pepper when you need it.
