How do you put away leftovers in the Sims 2?

In The Sims 2, to put away leftovers, click on the fridge and select the "Serve Dinner" or "Serve Lunch" option. If there are already leftovers in the fridge, your Sim will automatically store any uneaten food from their current meal into the fridge as leftovers. Additionally, you can manually place food items from the Sims' inventory into the fridge by dragging them over the fridge icon. This ensures that your Sims can enjoy their meals later without wasting food.
