<human>:  What quick and easy recipes can I make out of leftovers in my fridge?
<bot>: One quick and easy recipe you can make out of leftovers in your fridge is a stir-fry. You can use any combination of vegetables, cooked proteins (like chicken, beef or fish), and sauces to make a flavorful dish. Another simple option is a frittata – mix eggs, cooked vegetables, and cooked proteins and bake in an oven-safe skillet. Another idea is to use cooked rice or quinoa as a base, and mix it with vegetables, proteins, and a selection of spices.
