How do you give food to starving children in sims 3?

You click on your refrigerator or on your stove. There are two options. 1. Have Food or 2. Serve Food. Pick the Serve Meal icon and then what recipe you want to make. This will have the selected Sim prepare the food. When you are finished click the plate of finished food and an option will appear to call guests/household to meal. Choose that.
