I’m a huge fan of adaptable pantry recipes - meals that allow me to make as few trips to the grocery store as possible and just cook according to what I have on hand. Lentil soup is a great one for this, as you can make it with whatever is in your fridge and it will still taste warming and hearty, as well as unutterably delicious (this is doubly true if you make a batch of warm biscuits or cornbread to eat alongside the soup!)
