Vegetables might make you feel "differently full" compared to bread or pasta.
Here's a trick to see if you're really not satisfied, or if you're not yet feeling "differently" satisfied by your two vegetables: If you're still legitimately hungry, you'd be happy to eat, say, a second piece of meatloaf. If you'd pass on more meatloaf but would eat a piece of cake, you probably really are satisfied. You're just being tempted by a craving. It's a great time to eat a piece of dark chocolate.
