Eating a meal in a dream usually represents nourishment for the body, mind, emotions, or soul.

To dream you are eating may also just mean you are hungry or your blood sugar is low while you're sleeping.

To dream you are overeating or stuffing yourself may mean you're "stuffing" your feelings instead of listening to them, or that you tend to use food to substitute for real sources of happiness and love in your life.

To dream you are interacting socially at lunch represents everyday social interactions in your life.
