Still finding Thanksgiving leftovers buried in the back of your fridge? Put them to good use by incorporating them into a meatless shepherd’s pie. Maybe you have a few stray onions or celery stalks that didn’t make it into the stuffing — toss them in. Did you accidently buy too many carrots? No problem. This recipe calls for three. What to do with Grandma’s mashed potatoes? Repurpose them as the creamy topping on this hearty baked dish.

And if you’re not sure what to make with a lone can of pumpkin, Ellie Krieger’s Pumpkin Muffins are a sweet, spiced option for an easy breakfast treat or after-dinner snack.
