Mushroom & Spinach Stuffed Shells

Need a recipe that’s easy on the budget and also easy to put together? Try my recipe for Mushroom & Spinach Stuffed Shells.

This one is meat free but the cheesy filling is so yummy, you’ll won’t care that there’s no meat. If you have a crew that just can’t do without the meat, you can always add in some cooked shredded chicken or Italian sausage.

My guys will eat anything that combines pasta and cheese so even though there are “green things” in this one they still gobble it up!

What’s also nice about this one is that you can prep your shells ahead of time and then just toss the whole casserole dish in the fridge and bake it when you need it. My recipe makes a ton of food so you can feed a big group or enjoy leftovers. I love recipes that allow me to have a quick and easy lunch the next day…less work for me!
