I take every opportunity I get to stuff, melt, drizzle, and sprinkle cheese in my dishes. So when I get to stuff and melt cheese in these spinach, pesto & cheese stuffed shells, I am a happy camper.
These shells are overflowing with flavor. Simple frozen chopped spinach, delicious herby pesto, and ricotta, mozzarella and parmesan cheeses make it the beauty that it is. If that doesn't sound heavenly to you, then honestly we can't be friends (jk, but really).
So, if you're looking for a cozy and easy weeknight meal, this is it. Working time is about just as long as it takes for pasta to cook, then you put it in the oven and let it get all melty and beautiful while you chill on the couch and drink a glass of wine. The smells start to fill your kitchen, and shortly thereafter, the flavors fill your stomach.
I tend to prefer these spinach, pesto & cheese stuffed shells on the vegetarian side as is, but if you'd like to sauté some ground chicken or beef and mix it into the cheese mixture, by all means! You just likely need to make a larger hole in the bag when filling the shells.
